I have been on T3-only for 18 months.Most of my troubling hypothyroid symptoms on T4 monotherapy have dramatically reduced.
My latest blood results show my FT3 is at the top of the range.
So why have I been experiencing anxiety & depression since September?My enthusiasm for life has dramatically reduced.My motivation levels have plummeted.I have insomnia & a big reduction in appetite & enjoyment of food.
When I have tried adding some T4 in,tachycardia & ectopic beats return.But is it possible I need some T4 to stay mentally well?
I have also lost a lot more hair since on T3 only
