That dose of Seroquel is very small typically used just for sleep and not psychosis.....do you also have sleep issues?

I've heard good things about Latuda also but if you're worried about weight there is also abilify and geodon....I highly recommend abilify if you can tolerate it....especially in your case because it doesn't raise prolactin in fact you can give it along with other meds to reverse the prolactin effect.

The only way to know if you still need meds is to slowly taper and try a med free period....that can take months.....if you're unhappy with your current med better to switch and then taper off.
