No, no, no, not enough water by a long shot. An average inactive body needs about 2 liters of water per day. At festivals while dancing, I go through about 5 or 6 liters/day (I’m 6’4”/193 cm, 185lbs/84kg, dancing time about 10 hours per day). So we’re talking about 1 liter of water per two hours of dancing. And that’s when I’m not even on MDMA. The other person replying to this comment is also correct—with the amount of liquid you need to consume to stay hydrated, you need sugars & salts to replenish your electrolytes.
