You'll need to create a plan for sobriety which will involve changing your behavior.
1. You should check in with you doctor about how well you are physically and to seek advice in case you experience withdraw symptoms.
2. Read SR and learn about options for support (AA, therapy, etc).
3. If able, I believe in exercise in any form (gym, yoga, running, long walks, Pilates). It helps dampen my anxiety and makes for more restful sleep.
That will get you started. The longer you're sober, the more you'll learn. And if you have any questions or concerns, post them here. There are plenty of people ready to assist you along in your journey.
Trust me, if I can get sober, so can you. Wishing you the best.
