******UPDATE******
Shaved head at 80. At a half inch of growth sent another pdt90. Got results today and passed. Clear of all substances. In all I took 110 days clean and no treatment. Was a daily heavy user prior. (Sarcastic cough here...) Thanks for all the expert advice. Back tracking pages upon pages doesn't help much seeing that most hft ?'s don't get answered. Someone could use this as a reference......
