After trying a few different anti-depressants for my migraines, my neurologist decided to try
Effexor. Within a matter of few, I began to experience side effects, including weight gain. When I questioned my doctor about this, he felt it was unlikely that Effexor was the cause. So, I assumed it must be other meds I was on and continued to take it. Well, the side effects, including the weight gain worsened.
