major depressive disorde
"I'm currently on venlafaxine, 300mg/day, and have been on it for 6 months now.  This stuff works beautifully for me.  I had/have MDD, GAD, SAD, and took Paxil for 10 years, which worked quite well until 8 months ago.  I was scared of switching because of the fact that not all anti-depressants work for everyone, and I was terrified of fully reverting back to my suicidal, petrified old self.  My psychiatrist was able to convince me after a couple months to go for it.  On the venlafaxine I feel calm, HAPPY, able to concentrate, mildly euphoric, and better than I did in my early days of taking Paxil.  This stuff is hit or miss for different people, but don't be scared to try it if you haven't.  And give it time to work."
