I am at my wits end with my son. He is almost 10 and still wet's the bed!!!! Please help me!?

I have tried everything. No water after 7 pm, taking him before I go to sleep, Night time diapers (he just uses that one as a crutch), talked to the doctor more than once, I even got a pee alarm (he sleeps through it!) I can't take it anymore! He just sleeps so soundly and doesn't feel it. Any suggestions? Don't get me wrong I love him to death, I just am tired of cleaning up pee!
