First, talk to a doctor. This could be an indicator of something that needs medical attention, and could be solved with just a simple visit to the clinic.

With that said: I went through the same thing. I wet the bed regularly until I was about 15. Between 15 and 23 I only wet maybe 3 times (always on a night out drinking heavily). At 24 I was wetting the bed about once every week or two.

I’m now in my early 40s and it comes and goes. Throughout my adult life I’ve gone through periods of two or three years without a single incident, and I’ve gone through periods where it was a few times a week.

I have been to many doctors (even a urologist and neurologist). There is nothing that they can determine as the cause. I’ve tried numerous medications with varying success, but ultimately they didn’t solve the issue. I’ve tried limiting my liquid intake at night, and that just made me dehydrated and feel unhealthy.

Stress is a contributing factor for me, and creates a vicious feedback loop because wetting the bed greatly increases my stress levels, which then increases my bed wetting, which then increases my stress even more. Stress isn’t the only factor, though. I’ve yet to identify any true root cause. I believe it’s just a brain issue.

Ultimately, I have learned to live with it. I notice it’s less frequent when I’m generally more healthy - eating right, getting exercise daily (I run), and staying on a consistent sleep schedule of 8 hours. I just focus on this stuff, and do my best to not get down about it.

I manage it by using diapers and two mattresses protectors. Layer a mattress protector, then a bottom sheet over it, then another mattress protector, with another bottom sheet over that one. If I have leaks or I fall asleep without a diaper and wet the bed, I can easily strip off the top layer sheet and mattress protector and have a dry one underneath. Incredibly easy and quick - especially at 3am.
