For the past 2 or 3 years, I have had trouble falling asleep every night. It would usually take me about an hour up to 4 hours after getting in bed. Due to having to wake up at 6 every morning for school, this sleep problem wouldn't do. So i started taking whatever i found in my house to help sleep. (Tylenol PM, Advil PM, Nyquil, etc.). Now whenever I take them I usually fall asleep in about 20 minutes, but when I don't it takes about an hour or more. Am I reliant on these medications to fall asleep? What can I do to end this insomnia?
