I drink a lot of sparkling waters, especially Polar waters, San Pelligrinos, Perriers and fruit flavored waters that grocery stores sell, usually under their own respective labels.
I drink diet soft drinks during the day, some with aspartame, some with sucralose and some with stevia, and, occasionally, a Tab (which contains saccharine).
And iced tea with meals.
Ironically, even after getting sober, I still drink a lot.
Just not the stuff that causes me to lose people, jobs and my sanity.
