I Have Insomnia

I thought after retiring (early due to bad back) that I'd sleep better..........WRONG! Rarely do I get to sleep before 1 AM...happy if it's by 2 AM. I take Limbitrol, Benadryl, Tylenol PM...... Seems this is working for now but am worried about the long term affects. Commonly wake in the middle of the night and stay awake for hours. I have a "sleep" playlist that helps (soft soothing classical pieces). Doesn't help that I have had 3 back surgeries and at times must sleep with a TENS unit on to distract my mind from the frequent pain.
