@philsmypharmacist: 1 in 3 Americans have a sleep disorder. Some facts that might explain why you’re so tired: Caffeine clears in 2 hours for some people, 12 for others. Teens need 2 MORE hours of sleep than adults. Waking up a few times a night? Normal. You go through 4 to 6 sleep cycles. Sleeping 6 hours for 2 weeks = the same brain fog as 2 days with no sleep at all. And melatonin takes 45 minutes to work. Taking it when you get in bed is too late.
