The last two nights I have had to go to bed early because I'm so cold my teeth are chattering but within an hour I'm kicking off the covers because I'm over hot. I don't have any symptoms of cold or infection but feel very drained in the morning.
I don't know if it's a Hashimoto's symptom or autoimmune, I've been on T3 only for a few years now and think the dose (60 mcg.) is about right.
