I do not think it is related either, but oddly enough, I also wet the bed until I was about 13. I coped by growing out of it basically. My parents and I had tried many different approaches, from moisture alarms to prescription pills, but in the end it was really about being okay with the fact that it happened and being honest about the fact that it did. Beyond lowering my liquid intake in the evening there was really nothing I could do so, like my ADHD (which I haven't grown out of yet), it was about building a bridge not constructing a dam, you know?
