When I first got sober, it all seemed too easy. The thought of consuming alcohol made me nauseas. Besides a few disturbing drunk dreams, I didn't have any cravings. I'm in AA and I saw so many people around me struggling. I wondered why it seemed so easy for me to abstain. I also had little trouble accepting my status as a total alcoholic and addict, so I rarely had thoughts that I would eventually be able to drink in moderation at some point. AA has helped keep me in check.
I talked to my sponsor about it and the first thing he said was, "enjoy it, dude. Don't question things when they're going right."
But he also said that life happens. Things will inevitably come up that will test me. When that happens, I need to have the tools to deal with it.
And he was right; things did happen that tested my resolve. Major things that I was not expecting, from death of loved ones, to dealing with the end of a relationship, and finally my own serious and painful health issues. I'm glad I stuck close to AA and worked my program hard, even if it seemed so easy at the time, because when life happened, I was prepared for it.
