Was on Venlafaxine 37.5 for 8 days and could not take it at all. Stopped it cold turkey and this is my 3rd day without any. My question is how long does it take to clear my system because I want to start to wean off my Ativan. Been taking it for about 5 wks. I take it at bedtime and morning only. The dose is .05. I want to get my clear head back so badly. These 2 drugs have been a nightmare for me and can't wait to rid them. Any help would be appreciated.
