Hello. Sorry to hear about your hypo- problems. I have them too.
I was diagnosed 3 years ago was taking 50 mcg of levoxyl until a few months ago. I went to a new endo almost 6 months ago and told him how miserable, cold, depressed, unable to lose any weight even after running three marathons, hair falling out, puffy face, loss of libido, absolutely no energy, etc.. I convinced him to write a rx for cytomel (5 mcg) to use along with my levoxyl. Immediately I felt better I had more energy and I was actually happy until this last month. I think I need more cytomel. I read alot about it and alot of hypothyroid people are having great success with it.
The problem is the dosage has to be administered in such small amounts because it could be dangerous if you are given to much too soon. Also i've noticed I feel much better if I have smalll snack like meals avery 3-4 hours instead of a large meal. I run every other day and it seems like the only time I really feel good is while I am running. Good luck.
