I had a drug/alcohol test done at 38 days sober from alcohol as well as a hair sample taken - the hair sample came back negative (which I have never been a drug user), but I was informed today by my social worker that there was minor amounts of alcohol detected in my blood.  I KNOW that my last drink was 45 days ago - I went to treatment and have not had any desire to drink nor have I drank.  How could this happen?  I am due to go to court on Friday to start the process of getting my kids back and now this - the only thing that I currently take every day is 20 mg of citalopram.  My last binge was 12 straight days before I stopped drinking 45 days ago - I am 103 pounds and 5 foot 3 inches and I am a female - is there anyway that these minor amounts are still showing up due to my last binge being so long?
