Zoloft
"Took Zoloft for depression and anxiety and was on it for about six months. It absolutely helped and I felt less anxious almost immediately. But I stopped taking it due to increasing negative side effects. I have learned through my journey that other people's experiences of these kinds of meds are no real indication of how it will be for you personally. But sometimes it helps to share. Just take everything with a grain of salt. 
Zoloft negatives: constant yawning, first three days you feel so unwell you think you'll never be ok again.  Also, inability to have an orgasm, which lasted about three months and then I was fine. Serious vertigo that got so bad I had to stop taking it. 
Tried venlafaxine and Prozac with better results."
