You should drink through out the day, I try to drink on the hour to create a habit and more easlily keep track. You will be intaking minimal calories and nutrients so pace it...drink as much as you want through out the day...I shoot for 10-12, or half of my weight in ounces. Do not lapse for more than two hours or you may get very weak. My be your pops problem...
