I was diagnosed borderline hypothyroid 7 weeks ago. Have been taking 50mcg Levothyroxine. I felt amazing for a few days- wide awake, warm with a return of sex drive that I haven't had for years. Then it slowly petered out and now I'm back at square one, freezing cold, falling asleep etc etc. I had my bloods done last week and will get the results this week and I'm trying to inform myself of what's going on.
Can anyone explain why I felt so much better then it stopped? My TSH was 4.7 and the upper end of the range was 4.2.
