Hi Lilly,
Welcome to SR!
Myself, I don't commit to programs or techniques or meetings or whatever. I really do though commit to myself as a free agent with options, lol.
Seriously.
I think commitments can be greatly misused and abused. To each their own of course though, no problemo. FWIW, I've been doing AA and AVRT freely and as I choose with great success.
Is commitment a tool of recovery? I think not. Commitment is a personal challenge and enjoyment when successful, and is not limited to recovery efforts.
I would suggest there is no downside to commitments when we take ownership for ourselves and not also for generalities of whatever else may be on the day's menu.
Recovery is a choice, and everything following that initial original choice are as well respective choices in themselves. I'm very committed to my happy and successful life, and this then would be sufficient to include my recovery without further commitment to whatever recovery efforts.
