several years ago, i took the pink pills (effexor) for my sanity (yeah, i had to take them twice a day at exactly the same time or otherwise i'd get really weird), and just like muran, kicking them was one of the worst experiences in my life, too.
every time i moved my eyeballs, my brain had a delayed reaction. i was seriously scared to cross the street as i did not trust my brain to process things around me properly. it took me a very long time to come off them and even though they worked wonders while taking them, i'll never take them again.
