I want to switch from venlafaxine to Sertraline. The doctor wants me to come off the venlafaxine and take neither for 2 weeks but I don't think I can do that. I currently take 75 mg venlafaxine slow release. My plan is to take half a sertraline 50 mg e.g. 25 mg (or even less) for a week or so at night, to deal with the sleepiness, and reduce the venlafaxine by one pill in the capsule (e.g. 62.5 mg). I need to know how safe or dangerous this would be.
