"giving up" booze for a time is part of an A's denial
My husband told me he was NOT a drunk because he spent 9 months in Kosovo back in '99 and didn't have the craving at all. HELLO ... THERE IS NO LIQUOR AVAILABLE TO ANYONE IN KOSOVO, CIVILIAN OR ARMED FORCES! Of course, now that he's home all he has to do is get a sniff of vanilla extract and he's guzzling every drop of booze he can get his hands on.
I've watched my husband stop drinking after a particularly nasty bender, when he's come out of detox (maximum sobriety time: 40 days), and when he's deployed to a Muslim country. At this point I don't much care for him whether he's drunk OR sober. Basically, he's an emotional train wreck either way.
I no longer have expectations. Why should I? He's behaving like a perfectly normal drunk. To expect anything else would be MY fault! I hope your husband remains sober during Lent and, for your sake, I hope he is more pleasant drunk than sober.
