Before I began taking Synthroid, I experienced extreme numbness in my fingers and toes, a huge *HUGE*
weight gain, lethargy, depression, and hair
loss (to name a few).
You didn't say how long you have been taking the medication nor how much weight you have gained. I began gaining weight about 7 years ago and then gained over 70 lbs during my last pregnancy (compared to the 25 lbs I gained with the first two).
