Vraylar & sleep

I've been taking vraylar for 3 weeks and I wake up each night at 3-4am and can't get back to sleep.I also have nightmares every night and wake up every 1-2 hours. I was on abilify before and had the exact same problem and it never got better. Did you experience something similar while being on vraylar & did it get better over time or did you find anything else to help you sleep better? I'm also on vyvanse + guanfacine (ADHD meds). I exercise daily + walk my dog but it doesn't make any difference.
