I took Vistaril for one month, then stopped, Seroquel for three, then foolishly stopped suddenly (silly me), then Neurontin for two days (didn't work on me) until finally they tried Depakote and it works. I started to feel weird on the Vistaril. They are saying now I only have insomnia and reversed my diagnosis and want me off all medications. Great. Thanks. After a long time on drugs. Now I am on a low dose 250mg of Depakote, that's it daily, what is causing my hand tremor 2 months spaced apart of only being on Depakote?
