Hypo and been on medicine for over 9 years. Changed antidepressants 3 weeks ago from Lexapro to Bupropion Xl 150... Bad insomnia hit this week... up for over 36 hours. They gave me Lunesta 3mg. I have taken 2 nights in a row and sleep well. Then today Pins & needles in arms, legs, feet, and head. should I be looking at thyroid again and not the new meds?
