I saw just yesterday that for the "average" person it takes about 7 min to fall asleep. I was so in shock that my mouth dropped open, literally. The same post said for people with mental illnesses the average is about one hour. I still was in shock.
I never have been able to fall asleep faster than two hours. Usually I toss and turn for about four hours before I can sleep. Doesn't matter what medicine or drugs I take.
