This probably affects people differently.

I know people who can have coffee and fall asleep immediately afterwards, and have little to none urinary symptoms at all; and other people who’ll not sleep and / or need to pee frequently.

Personally, I find tea to be a much stronger diuretic. Even herbal tea (zero caffeine). Coffee used to cause diuretic symptoms, until I reached the point where I drank it every day. I drink tea most days now, but the diuretic effects never subsided.

/rant. Bodies are weird.

Note that herbal tea also has zero tea in it usually and so shouldn't be lumped in with tea either.

Perhaps your symptoms are psychosomatic?

It wasn't the urination for coffee that I'm referring to with these bathroom trips, I'm talking about number 2. Maybe I pee about the same, but I'm no longer cramping up and speed walking to the nearest stall.

Only if you arent adapted to it and you are given lots.
