I am in Pennsylvania. Initially, my program used LABCORP and then switched to RecoveryTrex. 4 years now and close to the end. It becomes 4 years as a result of the many many many signatures on your contract (here in PA anyway). We always did M-F. I have had two dilutes because I, too, work out and drink too much water. I have had a "shy bladder" and had to wait in the office for hours until I could urinate; BE CAREFUL -- I had a positive last year and had to pay extra to get the split read -- it was sugar -- I ate ice cream the day before. It was god-awful. I just rec'd a letter in the mail saying I was positive with no explanation (on a Saturday of course when no one is available). I was freaking out thinking someone tainted my urine (paranoid as hell with this program) and it took about 4-5 days to find out my split verified I was negative. I have aged a thousand years. I remain clean and sober and it will be 5 years in May. I waited a year to notify the Board -- I wanted my DUI court nonsense completed first. Stay the course my fellow travellers. Stay on your beam!!
