Been diagnosed hyper since October. I'm taking 20 mg carbimazol. I was up ALL night and in the morning was rushing around cleaning etc I thought I would be tired , but I kept going ALL day!! My friend said it was an adrenaline surge!!?? Does this happen often? Also I'm getting worried as I'm putting on weight rapidly 8 lb in two weeks!!! So I'm going to book doc appointment on Tuesday , but shall I reduce the carb in the mean time ????
