I agree. My b/f was hiding his drinking at the end of our relationship (once I'd told him that I would leave if he didn't get it under control). He would throw out his anti-alcoholic meds (campral, I think they were called) in the morning instead of taking them (why??? They were supposed to cut his cravings way down. They did when he took 'em.)
Then, on the way home from work, he would drink hard in the car all the home. He'd get to my house and have "just one." I coudn't figure out why, right after work, after just one beer, he was so messed up. It turns out, he was drinking that "just one" as soon as he got in my door so he could account for the alcohol odor on his breath. I figured it out when he would still smell alcoholic the next morning. No way that you would still stink for 12 hours after "just one."
Alcoholism is a sneaky disease. I bet she's boozing somehow.
