I'm taking Synthroid but the only symptom of thyroid problems I've ever had is my age :-) and I'm too tired sometimes. I was borderline for awhile with my blood tests but then there was a clear high one so my GP put me on the Synthroid. It's not a very high dose but I still have problems with Jeff Foxworthy's favorite symptom from TV med advertisements. It's not fun/pretty. I'm hoping when I go see him again the end of the month to get that straightened out.
