Maybe if you drank only ultra pure water and ate no food. The osmosis story is clear BS. The instant the water hits your mouth plenty of bacteria and electrolytes from salivia are reintroduced, not to mention all your digestive juices. If you injected the pure water directly into your bloodstream, you'd have an osmosis problem, thus the need for saline in IVs.
