Tapering off Hydrocortisone

Hi,
This is my first time posting.
I am a Thyroid Cancer survivor of 4 years and need to take NatureThroid 2 grains per day. I am kept hyperthyroid. My doctor recently checked my blood serum morning fasting cortisol level, which was 15.1. He then stimulated it and then he retested it 30 minutes later, which put it at 24.9. He said that with my symptoms meant that I had Adrenal Fatigue. He started me on Hydrocortisone 15 mg. (10mg with bkfst and 5 mg with lunch). I didn't realize the magnitude of this medication as he told me it was extremely safe, no big deal, wanted to put me on it while breastfeeding (I refused), subreplacement so wouldn't effect my own adrenal functioning, etc... so I just took it-- kind of willy-nilly. I would take only 10mg some days if I forgot to take a second dose- and some days I took 5mg only, etc. So, at first I felt great on it with awesome energy. That was short lived... then I began to have SEVERE headaches that he said were unrelated with unbearable dizziness. This lasted a few weeks, but I feel better now. However, I am sweating profusely, started getting bloated, gaining weight, having acne, heart palpitations (maybe from thyroid), hungry, some stomach pain, and feeling anxious. I decided that I want to come off of it. He still hasn't gotten back to me on how to do that (I called 2 days ago and called back today). I have been on it a total of just under 3 months. So, I decided I would start only taking 5mg with breakfast as of yesterday. I did and then today I did another 5mg with breakfast (I think, unless I habitually forgot and took 10mg still not realizing the magnitude). Then I looked around the internet and found how SLOW it should be tapered and the magnitude. My question is.... can I go off of it? How can I do it safely? HELP please! To make matters worse, I am flying out of town in the morning to help my elderly grandather. OH NO! PLEASE HELP!!! I so badly want off of it. I wanted to take only 1/2 pill tomorrow and then 1/2 pill for every other day a couple times and then just stop! Can I not do that? I appreciate any advice you may have! Tweet
