Ending2: Make sure that you're not over-tired and that you're getting enough sleep before going out. [substeps] If you feel that you have been sleeping for an entire night and need to get up early the night before to make sure you get enough sleep it's better to get up late and sleep out later. Ending3: Make sure you get plenty of rest before going out. [substeps] You'll also need plenty of time before going out to parties or workouts, so try not to oversleep if you're going out and seek at least eight hours sleep the night you're going out. Ending4: Either way, you are probably not going to sleep early. Drinking also interferes with your ability to get r.e.m.
