PR)) This happened to my husband a few times. He'd try to pass it off as nothing, or eating a poppy seed muffin, but he was using his DOC.
You only have to do what you feel comfortable with. When my AH got kicked out of his half way houses several times, he had to fend for himself and did. And ended up in rehab for six months because he was basically homeless. And that was a good thing!
Hugs for you to get through today and not project for tomorrow.
