Hi Sad, The meds you listed I am familar with 2 of them the venlafaxine and the mirtazapine. The venlafaxine is what I think a very good and safe depression meds. Lithium, I am just so cautious when that name is mentioned. The best advice to give you is to make sure you follow up with a good pyschiatrist. Make sure you are comfortable with the person. And you can alway check with creditability of the professional through the internet. Also as with any drugs there is always the risk of drug interaction. And maybe the dosing needs to be adjusted. Take care and Tah Tah Peanut
