We signed up for P.I. and 2 years laters, my son is still wetting the bed. The canned "pep talk" letters and 'recommendations' were absolutely worthless. If we were late in submitting a bi-monthly report card, we received a not-so-nice letter from our 'rep' telling us that we 'had fallen' behind yet again. My husband and I were guaranteed that our son would be dry within 90 days - unfortunately after a year and half, it was extremely difficult to keep up the nightly 'exercises', face washing with cold water, etc. I highly recommend that you DO NOT sign up with P.I.
