I have trouble controlling my urine. i wet myself during the day sometimes. i am 30 year old male and exercise frequently(5-6x/week) and make sure i drink plenty of fluids (~12 cups/day). i been trying to cut down the water intake but i get thirsty?

There might be two separate problems here. Remaining thirsty when drinking such amounts of fluids is not normal and could be a metabolic problem. Regardless of fluid intake and amount of urine, such a bladder control problem is not normal at your age. See your family physician or an internist to start, and expect likely referral to a urologist for the urine control issue. Good luck.
