Try to consume most of your fluids in the morning and early afternoon so that your bladder will be less full when you go to sleep at night. Never restrict your fluid intake to the point of dehydration. If you feel thirsty or if your urine is dark in color, drink water.

If you must consume caffeine, try to limit your consumption to the morning and early afternoon. Do not eat or drink anything containing caffeine beginning at dinner time so that any caffeine in your system has passed by bed time. Avoid all caffeine consumption in the evening, as this can increase the chances of bedwetting and also affect your ability to sleep at night.

Most people urinate an average of six to seven times within a 24 hour period. [4] X Research source Training your body to urinate every two to three hours throughout the day can help get your body more used to passing urine during waking hours.

Double voiding may be particularly effective when combined with a restricted fluid intake and more frequent daytime urinations.

While a bedwetting alarm may not be much help at preventing accidents early on, they will help train your bladder over time. With continued use, your body will be able to recognize the signs of a full bladder and wake you up before you have an accident. If you use a bedwetting alarm that makes an audible sound, you may have to explain to your roommate (if you have one) what the sound is. It may be easier to remain discreet if you use the vibrating alarm, as this will not produce an audible sound.

If you have one or more roommates, try to do your laundry when they aren’t around whenever possible. Don’t put off washing soiled linens. Launder your wet clothing and bedding early the next morning before class so that they do not start to smell. Be sure to change out of wet clothing right away to prevent rashes and other skin irritations from developing.

Remind your roommate that your problem is a medical one. It’s not something to be laughed at or joked about. Establish your boundaries with your roommate. If you don’t want anyone else to know about your problem, make this clear and ask your roommate to be respectful of your wishes. If your roommate does find out (or if you decide to tell them), reiterate that you’re taking precautions and trying to correct the problem. Let your roommate know that they’ll never have to directly deal with your problem and that you’ll be responsible for handling it.
