Aellyce, I just spent a really long and unsuccessful time searching for that part of Infinite Jest where DFW (not the airport) writes about addiction to attending AA meetings, and how an addict/alcoholic can go into infinite regression to a small room with one chair, worrying about being addicted to sitting down.
There's no harm in going 3 or 5 times a day, if it gets you through a day sober.
Infinite Jest has some of the best writing on addiction and 12-step programs ever. Have you read it?
