I was reading some of the responses and noticed that someone (nurse) said that both t3 & t4 should be addressed at the same time. Iam exhausted, can't get to sleep, but if I do I wake often during the night. My eyes have bags (which I've discovered is part of hypothroidism) can't lose weight despite exercising an hour a day and monitoring my food (I'm a Weightwatcher member), but it's hard to maintain the loss, constipated, irritable and feel that I'll never get to eat a good meal again. Help! Does anyone else feel these things???
