A hearty welcome to you, Sobrietea. You have found a great resource here at SR that comes with a lot of support for you. I hope you continue to post and share your success.
I IS exciting to understand that you can, right this minute, make your Big Plan, and choose to never drink, or smoke, or use, ever again. You have what you need already to make this choice, and to make it stick. A life without addiction to alcohol, or to smoking for that matter, is something that you simply deserve to have. Demand it, and never allow anything or anyone to take it from you.
Best to you.
