3:00 is a special time for your body... seriously! I mentioned this once to my massage therapist and he said to cut out booze and to drink water with lemon in it for a week and then see if it got better. Sure enough, it did! around 3am, people with normal sleep lives, our bodies do a lot of dietary detoxing. By cutting out the caffeine and booze, and drinking lemon water to help your body perform this task, you'll be less likely to wake up.
