Zuzu, personally I can't moderate my way out of a paper bag!
But we all have to come to our own personal truth on our own. Here's the deal: if moderation works for you, then there's no reason why you can't quit for two weeks. Try it. If you can do it, then you can likely go without it. My sense is that you'll know the answer during those two weeks. If you're constantly craving it, then you'll need help from other people (AA or the like). If you're good without drinking, then you'll know it.
Also, a site to check out is SMART recovery. It doesn't work for me, but I know a lot of people who've had success with it. It may be more along the lines of what you're looking for.
Best of luck! Let us know how you are!
