The 90/90 thing has been around for a long time. Some people do it, some don't There are 2 benefits from that schedule. The first is that by going to a meeting every day you're less apt to drink that day. And secondly, psychologists have learned that your brain sort of "resets" itself after a 90 day period of behavior modification. Don't ask me why.
I'd suggest that you cash in on that high probability of attending another meeting. Having the Big Book is one thing, but it's more important that you have another alcoholic walk you through it. Ashleek had an excellent suggestion. Try to go to different meetings. You'll find that there's a lot of variety in AA and this will allow you to find other meetings that you'll get a lot out of. And if you don't like the Lord's Prayer, there's no requirement that you recite it. I've been to meetings with a lot of Orthodox Jews in the group. They prayed, but in Hebrew, and I'll bet it wasn't the Lords Prayer.
