this summer has been crazy, so we've already done that a couple times this summer...
And we definitely don't take any precautions lol, I JUST finished a 6 day bender yesterday, and throughout the whole thing we slept on average like 3-5 hours a night and drank hardly anything but alcohol... pretty much no water whatsoever. Ate when we had a chance, and besides that just partied hard.
Your body is tougher than you think it is. Of course, I had a terrible hangover on the last day! (that said, I do not recommend doing this haha, take care of yourself folks)
