Just wanted to post an update. I am still on my new meds and dose. I am overdue for a thyroid blood test. But I am feeling pretty good, so I bet my TSH has come down. Libido was crazy high at first, I was actually giggling during the day for no reason! DH was a little freaked out initially but extremely pleased overall.
Then it seemed to go a little flat but then rebounded again and is just about perfect right now. I expect there will be some ups and downs relative to my cycle. I cannot believe I was living like that, the difference is so profound.
I hesitate to share so much of this here, since it is such a private thing, but wanted to add a couple things that might help someone else. The way I experienced low libido (at least this last time, I have waxed and waned since my first pregnancy) I didn't even really want DH to touch me. It didn't hurt but just did not feel good to even have him touch my arm. I had to work hard not to flinch or pull away too quickly. There were a few times I did want some touch, but that was because I was sick or really upset about something, and wanted him to hold me (and a few times I *really* wanted to have sex, totally out of the blue, probably related to my cycle). So if you are experiencing that particular sort of aversion to touch, I don't know, maybe that is another sign that it *could* be your thyroid? Worth noting, I think. Also, and this is way TMI, but a friend once commented that now when she has sex (as opposed to when she was younger) she feels like she wants to take a shower soon after. I thought, hmm, I have gotten that way, too. Except, now I am not! It's like I am experiencing it as I did when I was younger! So no ick factor, for lack of a better way to describe it.
So, if it's not clear by now, I just want to say, if low libido is a problem for you or your SO, put it on the front burner *now*. DH and I were doing okay, but now things are amazing. I feel like a newlywed again and that is a nice feeling. And I am not just talking about the sex part, we had really grown apart. And all the other stuff just came back naturally with the sex.
