"150mg/day. The first med I have taken that has very effectively tackled BOTH depression and anxiety/OCD. I believe this is due to Venlafaxine being an SNRI med (as opposed to an SSRI), which more effectively treat anxiety and obsessive thinking disorders, as well as depression. 

Drawbacks include the usual limitation on being able to feel deep emotion, a feature in many meds, which is a relief to some people and a hindrance to others.

Overall, it has been an absolute lifesaver"
