"i started taking 75 mg effexor xr four weeks ago. i used to be extremely manic, impulsive, restless, aggressive, destructive, and all-around volatile. i&#039;m back to being a bubbly, happy, normal twenty-year-old girl. i sleep soundly every night for 8-10 hours and wake to the alarm the first time it goes off (both are firsts in my life). i can concentrate in school, and i have hardly any anxiety. i do tire easily, and i have lost about 20 lb (i was a normal weight to begin with)."
