I Am In Recovery. Was Addicted To Opiates For 8

I am in recovery. Was addicted to opiates for 8 years. Been clean now for 2 months. I stopped taking opiates and was getting suboxone when I could. 8 mg strips and cutting it into quarters to stretch it out a few days. Then worked off of those to completely clean. Now I don't sleep. Maybe and hr or so a night if that. Stay tired all the time. Don't want my PCP know about my past addictions. What can I do to sleep?
