"i am a physically healthy (runner) 25 year old male. i have never been mentally healthy, so i have tried antidepressants. i tried prozac and wellbutrin. prozac didn&#039;t help or hurt ,but it gave me dangerous mood swings. i was prescribed effexor 2.5 months ago. it seemed a perfect fit for me. i was wrong. i was on 75 mg each day. it actually made me sadder. i had no weight or sexual side-effects but had vertigo. the worst was crippling insomnia while taking it, and now i am close to 0 mg, but i still get night sweats and &quot;brain zaps&quot;. as i write this, i&#039;ve had 13 hours of sleep in the past 5 days.
