Well you already know you can't control frequency and intensity, or you'd be doing it.
It's a lot easier to simply quit drinking than to go from unrestrained boozing to drinking in "moderation"--whatever that is.
Would you even know what your wife considers drinking in "moderation"? Would your allowance of drinking under her definition of "moderation" even be consistent from day-to-day? I'd think it would depend a lot on whether you were being argumentative, or whether she is drinking too, whether she's in a good mood, etc.
Do you really want the future of your marriage to be on such soft, unstable ground?
