Can better methylation cause somebody to go from hypothyroid to hypERthyroid? I am wondering if that has happened to me. In helping my friend - I started taking extra B12/folate, added a couple antioxidants, reduced my calcium, took some GABA. I've been getting very nervousy, anxious, my heart is racing, unexplained bruising. I've gone back to what I took before. The one day after a nervousy day, I skipped my levothyroxine altogether and felt better that day. I'm going to get it retested but would like to calm down a bit and get back to normal first - I don't want them to to take away my levo if I still do need it and then I gain 15 pounds overnight again. I know some of you mention thyroid in various threads so can anybody provide insight to this?
