I'm two years sober and still try to make a meeting every day, sometimes two or three a day, but I'm at that time of year again when my kids are playing sports and I miss meetings so I can watch their games. I start to get a little twitchy after 3 days of no meetings!
You'll decide what works for you, and you'll know if it's not working. Like c'est said, cranky or edgy is a good indicator that you need a meeting.
