I started at 25mcg, then my doc raised it to 75 mcg. I had no trouble before other than lab results were high. With meds I had a few problems. With increased dose I have nervousness, feel almost like I am on speed when the meds kick in for about 7 hours, then I am so tired I can't keep my eyes open. I have a ravenous appetite and yet, have lost 15 lbs. Not good since I only weigh 125. I have terrible abdominal pain, sweating, a lot of hair loss, leg cramps and headaches (something I never get). My doc wants to raise me to 88mcg. I don't think so! What else can I take? I am checking into natural stuff now.
