I'm on Vraylar for bipolar, and it is amazing! Definitely one of the best drugs I've ever taken! The only side effect I had was nausea when first starting, and nausea when I upped my dose. I take it at night, taking it in the morning made me feel kind of 'off'.
I honestly wouldn't worry too much about the side effects -- all psych drugs have a laundry list of them, with half of them being very serious. But it's rare for the very serious ones to happen. Things like nausea, dizziness, sleepiness etc. are much more common.
If you've got any other questions about Vraylar, I'd be happy to try and answer them!! And welcome to PC!
