Quitting was pretty easy for me too. I was a weekend binge drinker, so going all week or beyond has never been a problem. But I have also failed after almost 5 years of sobriety, so I don't assume it will remain easy permanently. Where I went wrong before was being too confident in my ability to be around dangerous people and situations. In short I ended a relationship with a girl who was a very modest drinker, and started dating a party girl.
