I am also on haldol and have been for about five years and it works great anyway that’s besides the point, I started Vraylar on Friday and as I write this it’s Wednesday night I am on 1.5 mg I am going to go the full 30days before I judge so far the only side effect I am getting is insomnia. As this could be just the fact that I need to get used to the medication I going to give it time unless it gets severe, other then that no problems I can feel it starting to kick in but no thataputic effects yet
