How do I stop peeing at night?

When I was little, about 5 or 6 years old, I was diagnosed with UTI. I've had peeing problems during the years, but it gradually became more normal as time went by. I just find it annoying that I almost always wake up by 3 or 4am in the morning to pee. Is there anyway to stop this? I heard diuresis (or was that just diuretics?) could affect your memory. Is it true with UTI? Is there a way for me to be able to stop waking up early in the morning to due this and finally experience a nice uninterrupted sleep?
