Hi CajunGirl -- I also have Hashimoto's and Lyme disease. I'm having a horrible time figuring out which is causing what symptoms! I'm playing around with different thryoid meds, too and am currently on 100 mcg Synthroid and 60 mcg compounded T3 daily. My Lyme doctor, who is also currently my Endo, said some people don't need T4 replacement at all, and actually respond badly to it, especially Synthroid. I tried removing it for a week and felt worse. But I'm going to ask him about Nature Throid b/c I was on it before. I think that + the extra T3 might be the thing for me. I think you should try Naturethroid, too.
Re: fast heartbeats, I've been having that lately too. Maybe it's a Lyme thing? I am on cortisol replacement therapy so it could be that for me too.
