I took cortef - switched to compounded hydrocortisone because the cortef hurt my stomach. Please, please read the following before considering going on it.
Also, please get fully tested before considering what to do. I didn't read all the posts in this thread so you may have done this alread, but get your thyroid fully checked and try the underarm test (you can google that for directions) which can be more accurate than blood in many folks opinions.
