This is a wonderful choice, and I wish you luck with your sobriety! You are losing nothing, while taking back years of your life, reducing your risk to all cancers by an insane margin, and saving a whole lot of money with how insanely expensive alcohol is.
If it might be any help, I would recommend buying a small stock of your favorite soda in their original forms (these can be easily found in most grocers, and they will be in glass bottles with Spanish on them as they are made in Latin America). Those bottles use the original formulas with five ingredients max depending on what soda it is (Usually Carbonated water, cane sugar, caramel for colour, phosphoric acid, caffeine), no nasty chemicals/corn syrup, and absurd amounts of sugar, while tasting leagues better then the American versions. Whenever I've ever felt like drinking, I'll pop out an cold latin Fanta, and I almost always lose all desire to drink as the taste and carbonation hit the spot perfectly.
