"this med. is a double edge sword. my dr. prescribed vistaril for my anxiety. it took 3 weeks to wean off clonopin----never stop cold turkey. by the 3rd. week i was only on vistaril. at 4 weeks the vistaril was working better than anything i have ever taken for acute anxiety. i was truly amazed and happy. so why did i only give it a 5 rating ? ? ? a dramatic increase in appetite and a even more dramatic weight gain. 13 pounds in one month. as good as vistaril works i am going to have to go off of it. in 15 years i have gained no weight and i have not experienced hunger like this in my life. so, i will ween off,  then work like crazy to shed this weight...not looking forward to that.  i am sad :("
