I normally drink at least 64 oz of water a day. Not that big of a deal.
You're right. I think that everyone is confused by "glass" of water. Eight ounces is a cup - the size of those little white styrofoam coffee cups that few people voluntarily use because they are too small. It's really not that much fluid spread over a 24 hour period.
I’ll go ahead drinking plenty of water anyway...I had a DVT (clot) in my leg last year. With none of the risk factors, not drinking enough water was a possible reason.
Also, if alcohol isn’t dehydrating, what about hangovers? Isn’t a hangover just dehydration?
