I have taken
Fiorinal (just like
fioricet but w/
aspirin instead of
tylenol) and the butalbital is somewhat intoxicating and it feels similar like alcohol, gives kind of a drowsy, off-balance, lowered inhibitions kind of state, but it was pretty subtle. But it is certainly not something that I could see people really abusing. I definately would be angry too, I totally understand. Getting your own test was the best thing that you could do definately, I would never trust my employer when it comes to doing the re-test (you never know when something is rotten).
I hope that this works out for you and that it all turns out OK,
