Looking for signs and symptoms will not help to "predict" the possible occurance, nor help decipher whether the feeling good is a good thing or not so, because the same signs can be a positive occurance for someone and be negative for others. Don't forget you can have an honeymoon followed by a rolling crash. The same good sign can be positive for a person one time and be negative another time. It has to be looked at in a broad perspective to have any relevance. Anyone can feel good for a short period of time, but it is the overall consistent recovery with less intense crash that we are looking for. Those who are self navigating should be very careful trying to extrapolate and be too self-confident. Its confusing enough even for inexperienced professionals.
Let me give you an example, hot flashes in menopausal women is common, and for decades, estrogen is prescribed because hot flashes improve is some ( but not all cases). In others, they get worse with estrogen. Why? because the same hot flash symptoms can come from estrogen excess as well as estrogen deficiency. Astute clinicians have known this for years ,and is very careful not to blindly prescribe without evaluating all the risk and finding out the person's intrinsic type and function but simply follow protocol and lab. lab is not 100%, don't forget. Unfortunately, most follow the lab and protocols, and millions of women in the past 30 years die of unnecessary cancer contributed by conventional medicine's protocolization and extrapolation without due consideration for the individual body.
Protocols of what to expect do not work in advance adrenal fatigue. The key to much of evaluation lies in the narrative history deciphered with time by experienced provider who knows how to understand, challenge , evaluate, and ultimately develop a feel of the body and confirm it. The body does not make it easy. It has a mind of its own and is set in its own ways for decades quiet comfortably. It take years to develop a sense on how to understand what the body is really saying, as in the case of what you mentioned. While a short feel good is wonderful when it happens, the key is what to do next, and that is the tough part. That is the part that requires a lot of understanding of what the body is really trying to say to you by this honeymoon. It could be the start of a honeymoon, which we will try to sustain, or it can be the last party before the crash comes, in which case we look at it as a warning sign. Everyone is different. Just as it is common to have some honeymoon along the way as well as some crashes along the way. Our overall job is to make the good times last longer and the bad times shorter.
Along this line, I must warn you since your question mentioned others that I see a lot of posts on curezone admist the best intention of many trying to help fellow humans only to confuse them further and inadvertantly doing a disservice because they themselves do not understand what is going on fully but guessing at best, yet they are sharing information as if there are universal truth to a very complex situation without many important qualifications. Everyone is different.
I dont know who is taking care of you, but I hope you stay with your doctor and try to spend more time following instructions. If he is good, there would not be anything you could ready that he or she has not read. so why reinvent the wheel ?
I see many trying to second quess or trying to be a doctor, both of which is negative for recovery as both can drain them of a lot of energy. Those who have no faith in their doc should change. Do not stay with any doc one has no confidence in, me included , when it comes to Adrenal Fatigue. It will be disastrous.Do absolutely make sure beyond any doubt as to the real problem - one's lack of patiences and not following instructions, or not qualified doctor. Jumping from one to another is very very harmful. It is easy to blame the doctor for our shortcomings, but in the end, our body suffers.
The same for me as a professionals- if I find those who wish my help have no confidence in what I am doing or not following my advice, I will say goodbye whether they like it or not. Its tough enough to deal with advance adrenal fatigue as it is.
There is nothing more dangerous than half-knowledge in health. You asked what appeared to be a simple question, but it is not. It is a good question. I hope I have given you some parameters to digest and have a better sense of the big picture which is what really counts. so much of the day to day struggle is to figure out all the small and minute symptoms it is easy to be buried among the symptoms. This is the struggle we go through each day trying to help others understand their body as the long term solution when the common and predominant thought process is get well fast and request for a cookbook approach which straight foward answers as if this is simple mathematics which have been a failed approach for years.
Needless to say we tend to say goodbye to those whose expectation of recovery is far away from reality as we are not magicians but professionals who try to do what we can with a damaged body on hand without causing further harm. In the name of science, much harm has been done to our society when not properly used and sometimes abused. That is why a snapshot laboratory test is seldom useful in advance Adrenal Fatigue as correlation to clinical expression is quite low in severe cases. Also trying to expolate one persona's experience into another person also will not work. That is why Adrenal Fatigue is so challenging. Its not about the supplements alone and the reaction with or without it.
The supplements is but a facilitator of the nurturing process. Most good students on our program that is patience will find success over time because our focus is to stay focused on nurturing and not on symptom reduction. Vitamin C is but one of many tools. Its easy to focus on that as it is quantifiable, but we also make adjustments on other issues that include diet, lifestyle, making small ajustements to the body consistently to remove unncessary strain. Thus wehen you see some one say they feel better or worse for that matter, there is more that meets the eye, and each person is unique and different.
The body plays a big role. The same supplement can be good for one and toxic for another. The same supplement can also be negative for the same person along the recovery path. Because it is a moving target, the only logical way is to keep close monitor, sometimes once every few day to start if condition is severed, sometimes weekly and biweeklly if stable, but seldom once very few months as the body would have changed too much multiple times already.
Coming back to Vitamin C, I hope you can see that there is no straight forward signs and symptoms to watch for. Sometimes, feeling good after a holiday off is a prelude to upcoming crash as mentioned before. Sometimes it is part of a resetting process. Sometimes its part of the a crash to honeymoon phase explained in my articles on the web. You have to look at the big picture - the long history of the person and how the body nutrient reaction history, the current stressor load, how well the body clear metabolite, and challenge history etc etc. Only with multiple snapshots over a period of time are we able to determine what is really going on with confidence. Otherwise its simply guessing. This is what I have learned after years in this field and researching it.
The simplistic view of many trying to tie supplements as a cause to an effect, whether positive or negative, will not work. This is why the majority of recovery program fails. They fail to look at the total body. The assumption that in adrenal fatigue, one lacks vitamin C, and by taking vitmain C, recovery is assured too simplistic. Those who have severe cases will know from first hand experience it does not work.
Feeling good after a brief holiday from supplement ( not only vitmain C) is a small part of a bigger overall picture what we focus on. Sometimes we plan a holiday for them and restart to kick start the system to the next level with more supplements. other times we allow the rest to go on further. Still other times, we continue to reduce for a long time and eventually wean them off. Each person is different as each body is different. We know the physiology behind the supplements. What we don't know is how the body reacts, and only with close monitoring and time and the body's ultimate response will we know the true picture. We endeavor to teach each one, but only if they are sincerely trying to learn and have the patience. This is not an approach comfortable for all people, but we have found is the most solid, logical ,and successful we have to date. Dont forget that I see many many that are so damaged by other professionals we tend to be the "clean up " crew.
As much as I like to take big credit for those getting better after being off it for a while, we consider this part of the overall normal recovery process. We make the determination each time whether it is positive or negative, and we continue to help and prepare so that the overall recovery is a positive one over time and not a roller coaster ride down.
