I feel like I might be cutting in the middle of a convo, but I just wanted to say that I think it is smart not to change. In fact, at one point I was on the generic synthroid and didn't realize it, but felt the same old symptoms. I went back to synthroid and felt much better. Later I read that this med is one of the ones that generics aren't necessarily good for. Of course I don't know about other brands.
Also, it is good you are being proactive re: your TSH. My 1st RE didn't think it was a big deal and as long as I was in normal range (.5-4.5 or something like that) it was ok. My 2nd RE kept me at around 1 during cycling.
