No problem widgeon, glad to help.

As for the validation strips and 20 ng/ml tests, I can't say definitely but I've never seen either of them anywhere but online.

What will be your actual number of days clean?

I can understand being nervous with the physicals and xrays coming first, they always complicate the situation. The only thing that I don't like about your current situation is the 20 ng/ml cutoff, and that you've only taken one 50 ng/ml test.

How heavily were you smoking prior to the Dec 20th?
