dsack... thanks for the reply. That's a relief to me, I haven't been able to find any info on the subject elsewhere. I like my job, and I don't even want to fool around with trying to explain a positive for hydrocodone, even though I get my hydro script from a local pharmacy, so I'm switching to Ultram until the as-yet-undisclosed date I have to get a DOT physical -- I hope they send me soon to get it over with. Thanks again for answering, I appreciate it. Tramadol sure is a weird drug, "pseudo-opiate," but it sure works great for knocking out hydro withdrawal symptoms.
