Regulate your alcohol consumption.

Limit your alcohol intake to at least 4 hours before bedtime.
If you want to play at a high level and still hang out with your friends for drinks, then hook up with them for happy hour instead of an all-night bender.

Drink more water.
Because alcohol is liquid, it is absorbed swiftly into the bloodstream. You need to drink more water to help flush out the metabolic waste products left behind.
