Three days ago I took an Effexor pill prescribed by my doctor. I immediately had negative side effects. 17 hours after the pill I ended up in the emergency room where the gave me Ativan and sent me home. Still feeling extremely ill I went to the psych emergency room and was given something resembling benydryl. Now it has been 60 hours since I took Effexor and I am feeling in a cloud, still have dry mouth, and feel in a baby-like state. I have been assured that the drugs are "out of my system", but this scares me more. Any advice? Can one pill mess me up this much? Will effects be permanent?
