major depressive disorde
"I've been taking venlafaxine 150mg xr for nearly 3 years along with an antipsychotic to treat bipolar 2. Having tried all kinds of anti depressants this is the one that's worked for me. The down side is the withdrawal symptoms should you miss a dose but these go away as soon as you take it again. Dizzy spells/feeling drunk is the only way I can describe them. It has a short half life of 7 hrs which indicates that they have these symptoms.  I've had no side effects & would recommend venlafaxine over other antidepressants inc citelopram &  mirtazipine."
