I have experienced the same problems and this is like a nightmare. No matter how much you explain the situation, the people “in charge” of your life are not capable of even try to understand our frustration when you explain that you have not been drinking alcohol and they tell you that you are lying. This is a device that is not accurate and cannot read alcoholic beverages solely. I wish some day we all can get together and bring this problem to the agency in charge of this program in an effort to, at least, have them produce a device that works. It is beyond my comprehension that one minute the machine detects alcohol in your breath and one minute later there is no alcohol detection. This is not a helpful program, this is design to make a person fail. And in top of everything it makes it even more difficult to find a job.
