Drink plenty of water, sure you have to piss. The thing it your muscle rehydrate and the water flushes shit out of them a waste and you drink after piss again then you bladder and intestines are helped in pushing out the stuff that has not passed yet. Funny thing is diarrhea is from being low on water so drinking more helps digestion and gives firmer shit but not hard unless using meth or adderall or something along them lines. So you feel well rested even with waking since you'll crash again, also keeps calf cramp from happening all the time. Though you need some extra potasium and magnesium since water tends to let them work more "used up" and also flushes them and salt which beside the lies we go through quite a bit of if we really work during the day.
