I just got my test results; TSH 6.5 -Synthroid increased to 150Mcg. recheck in 2 months. Yes I am somewhat cranky about this....

Ed, the symptoms of Hyperthyroid are mostly opposites of Hypothyroid. Body temp high, rapid pulse, heart rhythm problems, sleep problems, hyperactivity among many others. Overdosing of replacement thyroid hormones can cause serious heart rhythm problems and even be fatal. As Eileen has said under treating can also be serious.

PS. Eileen, I find it hard to believe you ever had a weight gain problem. wink
