Just wanted to update that I'm feeling better today, but not 100%. I definitely kicked my autoimmune disorder into overdrive. I have become incredibly WEAK. Forget working 12 hrs and still getting in my Pilates workout, I can't even walk up a few steps without stopping to rest, and being completely short of breath. I'm experiencing PROFOUND fatigue and weakness, which is how I used to live before starting my thyroid medication. I guess I just have to listen to my body and slow down. I'm still losing weight, I always drop a lot of weight during flare ups... down to 106 pounds now. (Started off at 115... lost the first 5 on purpose, the rest came off as a result of being sick.) I'm sure a good 5 pounds will come back as water once I'm feeling better. I'm very dehydrated right now, my lips are cracked and dry. I guess I'm gonna have to call it quits for a while. At least until I'm healthy again, and then I'll start off slower. Instead of Pilates every day, maybe just on my nights off. I'll still be dropping in.. this is a great forum and I've learned so much. If I stick around, I won't be tempted to give up all together. I'm going back to the doctor's tomorrow, so if anything changes, I'll keep you posted.
