I've decided 2 pull an all-nighter 2nite. I think im gonna workout all nite can I drink Designer whey after?

I want to workout all night to see what will happen....and also cause i'm not tired! After I do that, when its like 5 in the morning is it apporiate for me to drink a protien shake "Designer Whey" cuz that's what i always drink when i'm done working out?.
