It was nice to see your message re reaction to synthroid. I am similar to you. After about 4 weeks into increased dose, I feel the nervousness the most. Yet, my bloodwork shows hypo and the endo says need to increase. I have felt lots of weird things too. There for a while I thought that I was cracking up but I know that this is all related to this disease. I sometimes try to remember what “being normal all the time was like”. It is hard to remember.
