I was on methimazole (tapazole) and the SSKI drops, but not the other 2. Just remember removal is just around the corner!!! Then, you'll be able to get off of the tapazole, SSKi, and inderal (with your doctor's approval on the inderal but your heart rate should very quickly return to normal after surgery). Mine went from a resting 100- 120 to 62 within days. Yes, feeling crappy while sick with Graves is definitely the norm!
I take brand Synthroid- didn't want to take generic as to make sure I had the same manufacturer every time I got it refilled and more for the consistency. For the most part, I'm doing pretty well. I've had one dose change. I started on 100 mcg for 6 weeks, then upped to 112 mcg and have stayed on that- got my levels normal. I started to feel better as far as the Synthroid dose around 3 months or so. Now 4 months out, all in all, I'm doing pretty well- definitely happy with my decision as, although not 100% myself from pre- Graves, definitely WAY, WAY, WAY better than when I was sick!
Good luck to you!
