M.S.
I went through this with both my daughter & son. After many trying methods such as stop all liquids, waking up several times to go potty and rewards for dry nights. It was quite frustrating and I was running out of patience. I finally talked to our pediatrician and we decided on medication. We did not experience any side effects with either child. I can't recall the name of the medciation but it was a tiny red pill and we used it for a small period of time. In lammens terms, the little light bulb that should turn on when they have the sensation just wasn't turning on at night. We were all very relieved when the bed wetting stopped. We were washing and changing sheets practically every night. My only regret was not discussing the situation sooner with the pediatrician. I wish you and your son the best in resolving this issue.
