True, but where IV bags shine is hydrating those that can’t drink water. (Vomiting, nausea, etc)
Even if the person has nausea, they can drink a bit at a time
> Second, she says, is to resist the temptation to drink at a normal rate—let alone chugging the stuff. An ounce at a time every few minutes decreases the odds that the liquid will, um, return from whence it came.
Not necessarily. Sometimes the nausea is so severe that even a teaspoon of water gets sent back the way it came in… a most unpleasant feeling when the body refuses to take anything and ends up vomiting fluids beyond the stomach—e.g. bile.
Having a needle in your arm for hours is not pleasant. My dad doesn't heal so quickly these days, so he's going to have bruising and tenderness for a week where they put the needle in. Watching my dad go through this, and my girlfriend's brother who has mental disabilities a couple of years ago, and now realizing it would have been a lot more comfortable for them if they'd just let them sip on some Gatorade seriously pisses me off.
You're being down-voted, but I know a number of military medics and hospital employees who do this after heavy drinking. Seems to work like a charm.
