I took half my sleep potion and substituted benadryl for the vistaril because I get such horrible restless leg lately. I miss using the vistaril though. It's a brilliant combo for sleep, but if something wakes you, you'll be very weakened in your body, and you could have some scary amnesia.
I like taking tiz regardless of whether I take the benadryl or vistaril. I think it's better with the vistaril, but the vistaril is useless for restless leg.
