Honestly, the toughest part of it becomes the sweetness of all the Coke. It makes me want to puke after about a good 8-12 large (20 oz. or so) Captain n Cokes. If I ever try to do it again, I'll probably try to swig a shot, here or there, right from the bottle, to cut back on the Coke intake.
Maybe I'll try it this summer once. I'll sleep in til about 8, eat a little, go for a nice run around 9 to really wake myself up, shower, and then start drinking around 10am. I could go for one big 20 ouncer every hour, with a good swig of Captain followed by food every two hours to get some more Captain down but more importantly, something in me and the sweetness out of my mouth.
You gotta plan this **** out. I may literally even weigh how much Captain I put into each drink so that I pace myself perfectly. There are 1,750 milliliters in a handle so I'd probably start with 70-80 milliliters of it per drink to start and reassess my situation every hour.
