also, with leakage, if it's heavier than expected, it could leak. as in, you thought you just needed a regular, turns out *oops* you needed a super, and 3 hours later, the regular is full, it could start leaking a bit.

the 8 hours is a good rule. but also, if you are wearing it for 8 hours, try the next absorbancy down. multi-pack boxes are crazy good.
