I have taken Venlafaxine xr 450 mg a day (225 morning and 225 at night). Doctor has started me on Trintillix at the same time, but I am terrified of the withdrawal from Venlafaxine. I have been on it for about 7 years, and times when I would miss my dose, I could feel the w/d's starting. I have been taking one less tablet for three days, so in three days I will be done with Venlafaxine. This seems way way too fast to stop this drug. How did you taper? Any suggestions on how to survive this?
