I keep a small amount of beer, wine, and sake in the fridge but keep back-ups of those items in the trunk of my car. Whenever my girl is out and I inhale a bottle of wine I just toss out the bottle in the neighbors bin and then replace it with a new one.
If she comes home when I am drunk I just act like I am asleep so she does not try to kiss me and then discover the smell of alcohol.
I have been doing this for about a month and so far so good

She actually thinks I am sober LOL (she knows I still smoke heaps of chronic)
Anyone else have any good tips?
