After drinking alcohol for a month i am now bedwetting can this be a cause?

It's a diuretic: Yes--alcohol is a diuretic which acts on the kidneys to make you urinate more often. There are of course also other possible dangerous effects from drinking too much such as liver damage and damaging effects on the brain. I suggest being very careful about how much you drink. I'd be glad to consult with you more in a private consult on HealthTap about this if you desire.
