How do you tell people you're thinking of quitting drinking?

I haven't been drinking for about a week and a half, but...

1) I'm not sure if I'm quitting for good or just until I get some stuff in order
2) If I tell people, I guess truthfully I am afraid of being held accountable because of 1).
3) If I don't tell people, things will eventually get awkward since I am a known drinker with friends and family who enjoy drinking
