How can I avoid peeing during a plane trip?

Chicago to Hawaii....I'm always in the window seat boxed in by sleeping parents and older sister sits in next row(shes in high school). I'm shy/embarrassed about having to make scene about going on the plane.How can I avoid peeing during a plane trip?The easiest way to avoid even thinking about going to the bathroom is to just sleep the whole way. Otherwise, don't drink many fluids beforehand, or ask to be on the outside seat as to not disturb people. A flight from Chicago to Hawaii is long, and you're bound to go the bathroom at least once, it's not a big deal.How can I avoid peeing during a plane trip?Go just before the plane loads up and don't drink anything on the plane while in flight. But I really don't recommend that. Having to pee is just a fact of life. Everyone does it. Just go ahead and go to the loo. No one is going to think anything about it.How can I avoid peeing during a plane trip?Keep the cup they use to serve you refreshment on the plane. When you feel you need to go, pee into the cup. When you're done, press the service button and pass the cup to the steward/stewardess for disposal.How can I avoid peeing during a plane trip?
Don't drink to much water and go right before you get on the plane.
