When I was 15, PCI rescued me from nightly bedwetting. It took about 9 mos. before I was officially declared dry, but it was worth it. Well, I'm 37 now and my 4 1/2 year old is on the program. She is a very deep sleeper (as I was) and wets every night (as I did). We've only been doing the program a week, but I'm a beleiver because it worked for me. I'll post again later how it works for my daughter.
