I have been on Levo since August and am now on 100mcg. At first I saw a bit of an improvement but now I'm not so sure. I had to see my GP last week for a review of my meds and I told her I am suffering badly with horrendous mood swings (I don't know how my husband puts up with me) and pretty bad insomnia. She offered something for both but I refused, then she took my blood again and said she'd ring me with the results. I'm trying to lose weight, and have joined Slimming World but progress is verrrrry slow as I've only lost 7.5lbs in 5 weeks and 5 of that was in the 1st week! I know it's a long shot without knowing my results but does anyone think an increase in Levo would help? Or maybe T3? My doc is pretty good and open to suggestion so I'd love some guidance if possible so I can get the ball rolling straight away when she rings. Thanks a lot.
