First flush DONE finally!!!!!

WOW!! I am so new to this that info kind of went over my head but thank you for sharing.
My first flush is over and I did not enjoy it at all!! First of all, fasting killed me. My body doesn't react well to that. I was sick with hunger but I did it, a tiny bit of milk in my coffee. The rest was fruit and bread with preserves. The ES were horrible. The thought of drinking that agian makes me think "NEVER AGAIN". The oil and lemon juice was even worse! I guess I need to figure out what will work for me because those drinks didn't !!
I finally started having BM's after the 3rd ES. I didn't check to see if there were any stones. I didn't have the stomach to dig around in that stuff and I am really in it more for feeling good. A few times I did see small floating balls but they were brown and not any different looking than the BM, were they stones?
I was starving so I went back to a normal diet asap. I was unbelievably hungry and ate 5 cookies about a 1/2 hour after my 4th ES drink. I couldn't help it, I was miserable.
I ended up with a horrible headache also. It is now the day after and I don't feel well. I still have a bit of the headache and still no energy which is why I am trying all of this. I know I cheated but this is torture for me.
I am hoping once I find drinks that aren't so bad, I will do better. Practice makes perfect, right?
Any advice, tips or experiances are welcome. I need to keep it simple. Like I said before, I have 2 year old triplets so my time and energy are FULLLLL!!!
Thanks all!
