I have recently been diagnosed with Hashimoto's disease and my dr. put me on 50mcg of Synthroid...I haven't really noticed a lot of the normal symptoms that everyone else has except the memory loss. Oh and one other very disturbing side-effect...FREQUENT URINATION! I never had this problem before I started taking this drug that I can recall and I've been tested a gazillion times for kidney infections and UTI's and they've all come back normal! This is so frustrating...please tell me I'm not alone! If anyone else has experienced this please reply asap....I need to know I'm not crazy.
