I have a problem taking syntroid. When my tsh level get toward normal, i feel like im getting too much. Sweating, can't sleep, anxiety, jittery etc... My doctor advised me to divide the dose. I take half in the morning and half in the afternoon. This has helped a lot but still can't get my tsh levels below 3.36. Get symptoms of underactive thyroid also. My new doctor does not know what to do. My former doctor has long since retired. Any suggestions?
