Tell me about it. In all liklihood it is the meds on top of not doing the safe diet. The safe diet should improve things noticeably, but your going to still feel like crap. You are going to ask yourself many times, "Is the cure better than the disease?" In this case it is treatment, not cure.
If it gets "under control" you'll be able to taper back on the drugs and get close to feeling human again, but you'll always feel "off".
If you don't get it under control the "cure" will be painful, and dangerous, but once you recover you'll feel pretty good again.
