I have trouble with the same thing, no don't know how to handle it properly. I know AW has been drinking because she is acting like it, but the words coming out of her mouth say otherwise. I can decide there is some approximate % chance that she has been drinking or she is telling the truth based on the events of the day. Then I find myself wondering if I should spend some time looking for evidence, because maybe I'll know for sure, maybe put my mind at ease with an answered question, like, ok she WAS lying, now I don't have to wonder if I was falsely suspicious.
I guess I have just talked myself into thinking this is crazy. We need to try to do step 1, just let go, admit and accept the powerlessness. I think I put my mind at ease more by writing this post then by searching my house for empty bottles.
