I am 20 years old and I would say I started drinking once or twice a week and age 17. My problem which just started occuring a little over a month ago is that when I drink alcohol, I guess mostly beer, if I have 10 or more in a night I end up wetting myself while sleeping. This has just occured recently and was never a problem before. I tested it out with water one day as well and drank a lot over a 3 hour period and then proceeded to go to bed. I woke up in the morning and realized I wet myself. Is this a prostate problem?
