I don't know what happened to me. About one month, I was overmedicated(on135mcg levo +1/4ndt) my ft4 was 24, 5<12-22 and my tsh was 0,12. Now i'm just on levo. About 4 weeks ago I reduced my levo at 125mcg but my sleep didn't improve, I can't sleep without pills(2,3hrs). I never had this problem before, I slept very well on levo with our without ndt or if I added t3. This sleep problem is slowly kill me. I can't get into a deep rem sleep. I'm very tired, lose my concentration, etc. Now my ft4 drops to 22 and my ft3 it is 4(it is low I know). My endo referred me to a psychiatrist who told me I'm little depressed and anxious maybe due to my levo medication. She offered me 6 month tratament with sertraline (zoloft) or buspirone (buspar). I never used this medications before and I'm a little scared. I don't know if those pills will help me sleep. I don't think I'm depressed and don't know what to do.
