I have been experiencing these for the last 2 weeks since increasing my T3 dose. I get them especially strong at about 5-6 pm every day.
Since New Year's Eve I have added some T4 back. It feels somehow more stable and good to have T4 in my system. I've cut down on T3 and now take only 20 mcg with 75 mcg T4, however I am still getting hot flashes. I am not perimenopausal or menopausal. My heart beat lowered a bit since adding T4 which is good.
Has any of you had a similar experience while on T3?
I must add I am not hyper at all, I still get my ectopic heart beats and other symptoms on a daily basis.
