Thank you for the replies! I talked to my doctor today and she told me they had to fight my insurance tooth and nail to get me on the Vyvanse in the first place and that they probably wouldn’t approve me for trying anything that I haven’t already. So, screwed there, I guess. She’s going to have me stay on Vyvanse and take a thyroid medication as well. My levels are within normal range, but she is hoping bringing them up more might help my symptoms. I’m doubtful of this idea, but I’m willing to try just because I’m basically out of options.
