depression
"Started on Pristiq after my dad passed away two years ago, and I was to the point I couldn't handle life.  It was great; I was happy, I could cope, I didn't gain too much weight (a little maybe, but I wasn't "obsessed" with food). My sex drive was pretty much gone though.  Because of lack of sex drive, and sudden migraines, I went off it after a year.  Tried to start taking it again, and it just wasn't working anymore.  The number one thing I would warn people about is that it's really hard to stop taking this medication. The side effects with the withdrawals are brain shocks, depression, blurry vision, confusion, exhaustion.  "
