When I go see a movie at the theater, I'll consciously avoid drinking fluids yet without fail,

How can I drink the necessary amounts of water in a day and prevent an inordinate amount of urine pit stops? I'm pretty sure diuretics make one go pee. Is there an opposite that I could ingest (or do certain foods/drinks have the antithesis to diuretics)? Thanks

Try going AT the movie, BEFORE it starts.
