Good and necessary start.
A Plan is nothing more than how to fill the hours productively and honestly without picking up a drinking.
Planning how to answer the questions. How to deal with social events. How to deal with emotions other than drinking at them.
You've got the most important part. Don't pick up that first drink and all the rest will be sorted in time.
For me it involved grocery shopping for good healthy food. Preparing, eating, cleaning up. Taking a long walk outdoors every day. Writing three things on my Gratitude list. Coming to this site and reading and posting. I started each day here, it set my intentions and helped me stay focused. Then I started working on my other issues as time went on.
