Each person is different. For some, 3 meetings a day is what they need. For others 3 meetings a month may be what gets them through.
The important thing to remember... get to a meeting before you need one and you won't need worry. When we get lax and start thinking we don't need meetings at all, we run a risk of starting up our old ways of thinking.
For now, I would say go to as many meetings as you can. Time and recovery will guide you to how ever many would be a good balance in the future.
One a week could be it. You will know when the time comes.
