Well, sweetie, if you're drinking pop and coffee and things like that after dinner, of course you'll be up all night peeing! Actually, if you're drinking that many diuretic beverages, you should probably drink more water. And I know you're tired of reading this sort of remark, but yes, I drink four to five litres of water every day, drink up until nine p.m. and only have to get up once during the night. I also never drink anything else, except two coffees in the morning and one in the afternoon.
