Wait 90 days?
I would ask your sponsor if they would work with you now rather then wait.
A talk with your Dr sounds like a good idea as well.
Keep trying and you will find the answers. 10 days here, 80 days there... each time we put together a few days, we learn a little more.
Try to think back on your thoughts on the days you make a choice to pick up that first drink. When we realize when, we can get a better handle on things that helps us not pick up that first one.
