Bum - I would hope the lab test is specific enough to show that no, you weren't on meth. I think when those quickie tests see sudafed it gets flagged because of the meth angle. It will probably be ok. I understand the worry, though. And the guilty feeling. When my interlock messed up last month I got a guilty feeling, even though I knew damn well I wasn't drinking. And I felt like I had to defend myself vehemently, because I'm sure some people figured I was lying. Maybe someday after enough time goes by all of that will fade away.
