i would like to know if after i had taken an overdose of tylex with a small amount of alcohol would it affect a breathalyzer test i was in a very bad state of mind mentally after the death of my dad and brother in the space of five days and having had a double funeral. i went for a drive in my car after taking the tylex and was pulled over by the police i failed a breath test even though i didnt feel as though i had drank a lot, but i had taken quite a few tylex
