No one can say how many meetings are right for you other than you. You'll know if 3 feels right. If you feel edgy or cranky then you probably need more meetings. Right now 3 is better than 0.
Very true...the 90 in 90 is just a suggestion...not written in stone. When I was newly sober, I made many more than the 90; but, I had the time, and needed to fill it with meetings as often as possible.
When I tried to make a lunchtime meeting and couldn't quite get there on time, an oldtimer told me, "Half a meeting is better than none."
It is said that "this is a selfish program", meaning sobriety has to come first, because without it everything else will be meaningless (or lost). You'll find a balance that will work for both you and your husband.
