My worst experience bloating I drank an entire 50 Fl oz poland spring bottle, felt incredible for a moment, then stumbled to my bathroom and puked. I felt perfectly fine until I polished off probably the last 10-25oz. Would not recommend, at least I have a personal point of reference for my capacity, however.
I'm sure body type has a lot to do with it though, be aware of your *own* capacity and listen to your body. As long as you don't do it all at once and break between chugs you can evaluate how you feel and if you need to stop.
