Hi I'm Jessica, I'm 23. I just started taking anxiety and depression meds on 8/13/12. I have been just having a lot of things happen in my life that have been bringing me down. I've never been a depressed or anxious person. My DR put me on 50mg Pristiq and .25mg Xanax. I never really taken pills before so taking these meds really made me nervous. My question is how long do I have to take them before I get additicted? That's my worst fear, I don't want to be on these for the rest of my life. I take one Pristiq in the morning and the DR wanted me to take 3 Xanax a day but I only take one in the morning also because that's all I need for the day. I'm just nervous about this whole situation. Any advise?
