Last week I was diagnosed with extreme anxiety disorder by a physcitrist... When I did more research I found that its more of GAD... I went to see my doctor because I have extreme case of insomia....(5 months) My mind races at night and just cannot keep my mind clear at night... My doctor prescribed Venlafxine ER 37.5 mg just wondering if anyone of you are or did take this medicine... How safe is it? What are all the major side effects? I'm also taking 10 mg of Ambien... Any help would be apprecied....
