"i&#039;ve had unmedicated anxiety all my life which seemed to become worse with as i got older.. though i lived with it. also i experienced my first migraine which were followed by almost daily tension headaches. my doctor recommended effexor. i was very nervous to try after the many things i read googling. i told her i was also concerned about weight gain and sexual dysfunction. i was a newlywed of 40.. worked hard to loose weight. she still recommended it. in a few weeks i could feel better. i noticed as time went on i was calmer.. i wasn&#039;t having 10 thoughts at once. i felt at peace. i started sleeping better. because i felt better and my mind was clear, i was more patient. sex was even better. i did not gain weight. a little nausea at first."
