In my profession we call it SideEffexor. It is a good drug but it is difficult to discontinue, just as Paxil is. It requires a long, slow taper to get off of the med. As with most meds there are always some side effects- slight nausea first few days, you gotta figure out if it will make you sleepy or keep you wake so you will know to make it a morning or evening dose. Haven't seen too much weight gain. Some women have night sweats, which is odd because it is presribed off label for postmenopausal symptoms. Personally I would only take it if I have failed all other classes of . Hope that helps. Good luck.
