Been on Pristiq for about a week 50mg. I was on Effexor 150mg previously and was on the 150mg for about 2 months coming from 75mg Effexor. I had to increase the Effexor because the 75mg wasnt working and I my anxiety/depression came back ten fold. I was put in a mental health rehab when the 150mg Effexor actually started working and I was feeling great!....Finally normal again. But the rehab Psych suggested switching to Pristiq, suggesting it metabolizes better and it was a cleaner version of Effexor. I went along with the idea just to please them and to get out of the rehab sooner. I did a quick taper dropping to 75mg for 3 days then to 37.5mg for 3 days while adding 25mg of Pristiq until I was upped to just 50mg. Its almost been 2 weeks and Im out of the rehab but I am now dealing with bad depression. I wake up late not even wanting to get out of bed because I have zero interest in anything what's so ever. I feeling hopeless at times as well. I dont think Im noticing anxiety other than social anxiety but I think that is just feeding off the fact that I have no interest in anything including talking to people. Is this common with Pristiq?
