Wetting the bed at night is a type of urinary incontinence called nocturnal enuresis. One of the causes of nocturnal enuresis is drinking fluids at night. Adjusting your bathroom habits and beverage choices can help you stop wetting the bed at night, even when you enjoy a nightly beverage.
Set a "beverage deadline" in the evening, a time past which you will not drink anything at night. MayoCinic.com addresses the problem of pediatric bed-wetting by suggesting that a child drink only 20 percent of his daily liquid intake after 5 p.m., a system that can work easily for adults as well.
Another option is to work backwards from the time you usually go to bed and stop your fluid intake 3 to 4 hours before bedtime to reduce your nocturnal bed-wetting.
Choose non-alcoholic and caffeine-free drinks in the latter part of the day to stop wetting the bed. The Merck Manual states that alcohol acts as a diuretic, increasing the frequency of urination and can also have a sedative effect on your muscles, making your bladder muscles weaker. Caffeine is an irritant and can cause urinary urgency as well.
Set an alarm clock to wake you up to use the bathroom at night. Make the first wake-up call for two to three hours after you go to bed. Try to wake up every few hours throughout the night to urinate so you don't wet the bed.
Speak to your doctor about adjusting your medication schedule if you take diuretics, drugs that increase urinary output. Taking a diuretic too close to bedtime may increase your chances of wetting the bed. Altering your dosing schedule may allow you to continue your nighttime fluid intake and stay dry without making any other lifestyle modifications.
