Hi I am new to this site, but old to GD. I have a genetic form of graves and have suffered its wrath for over 50 years. I had RAI over a year ago and have been mild to moderate hypo since. I have long wondered if exercise increases your thyroid function, since my graves syptoms seem to be worsened by heavy exercise. I was glad to find out I wasn’t losing my one blond brain cell. I am currently on 88mcg and crumble from the minute I take it in the morning. I too believe in not messing with the dose, but I am stressing my marriage so bad that two days ago I dropped it to 75mcg. The dose is good and I seem much more stable until I take our golden puppy for his walk and about 1/2 hour after we get home (it is a mile walk, far for an old lady), I turn into a raging manaic. I go tomorrow to have my colestral and thyroid tested. If anyone knows how to control the moods without drug treatment I would appreciate the advice. I have tested the patience of my husband of 32 years far to long and he is showing signs of the stress also. It is such a tough illness for everyone and I always feel so bad about stomping everyone around me. Thanks for letting me say this.
