A strange thing has happened...
I seem to be getting a rapid twitching chest in the early hours of the morning. I thought it was my heart pumping 10 to the dozen but I'm sure it's actually my chest muscles twitching. I had it before when I was on T3 only. I'm back on T3 only again and low and behold its back again.
I wake between 4 and 5am anyway- I'm told this is low blood sugar but what is this twitching on T3? Anyone?
