The ease with which this makes it sound like I can suppress an urge is misleading... I know that very often having that first "real" beer leads me to conclude that the day has just lost it's "dry" status, and my alter-ego might step in and say "Ha! you lost, my turn..." and away we go. As such de-alcoholised beer can be a pretty valuable tool for me.
As an aside, I saw an ad recently for Budweiser "Prohibition" de-alcoholised beer. Anyone try that? Currently my go-to in a de-alcoholised beer is Becks Zero. If you were to compare it in a side-by-side taste test with the original Beck's you could definitely tell the difference, but by itself it is pretty decent (though it, like the original, has a distinctly German hoppy taste, which may or may not be to one's liking).
