I’ve been taking T3 since the beginning of May. For a while I felt a bit better with a bit more energy. I still had days when I was wiped out but overall I think there was an improvement. But now I feel terrible. Really dizzy, tinnitus worse, headache body thrumming all over and weight on my chest. Endo has suggested I take a 20mcg tablet T3 at night and increase T4 from 75 to 100mcg in the morning.
