I suppose that i'm glad that i'm not the only one who experiences this. It happened a lot more often when i was a kid. Nowadays, when it does happen, it seems to happen before and not after.
What I've always wondered is what makes it so much more urgent sometimes when I've only got a few ounces than other times when I've got a quart to get rid of.
I theorize that those "few ounces" are far more concentrated and thus more toxic (to oversimplify the chemical activity going on in one's water), thereby causing more irritation of the bladder valve lining (and a stronger urge to relieve the bladder) than the more diluted and relatively Ph-balanced quart of waste water. Get too much in the bladder, however, and simple pressure will stimulate those "imminent micturation" signals.
As for the shivers, I imagine it may have to do with shifts caused by core temperature regulation.
Hmmm. Overall solution strength doesn't seem to be the difference, but I hadn't thought of pH. That would make sense--more acid, more urgent. I'll have to test the hypothesis by seeing if a glass of wine has to come out more urgently than a pint of bitter.
My sense of the shivers has always been that they're directly connected to the action of the sphincter. I bet there's just some weird little motor reflex there.
I've thought about that often, too. My theory is that it's as much a function of how quickly liquid is flowing into your bladder – if you've had a lot of water, you may feel the urge to pee even though the bladder isn't full.
