Need help

I'm six months off Fenty I'm in only 45 mg of methadone and I've got the worse insomnia I've tried Seroquel temazapam a foot pressure point scrub for sleep I use weed to try but nothing has worked I'm up every hour wake up in a running mode I like wake up out of the blue n all. A sudden I'm walking down stairs almost like how I used to knod off and wake up get up walk to the dealers for more so does anyone have any tips or advice I'm not wanting to go backwards because of this sleep loss
