I second Bex and SS on their advice. I was in your position 2 or 3 years ago and made it through with natural supplements and exercise. No coffee. Good diet with good fats. You will read it all on this forum.

You too with the lack of appetite? Yes, I went through it, dropped about 30 lbs. I was lifting weights, and was getting bulky at 210 or so - which was when I was hypothyroid, but before I got sickly toxic. Dropped down quickly, which was OK for me as I did not need to weigh that heavy. I believe your instinct will turn off your appetite if that is of benefit, and would not worry unless you are seriously underweight. Many days I did not eat much at all. You know that calorie restriction extends life in animals?
