I just read the book Unwasted: My Lush Sobriety by Sacha Scoblic, which is a memoir about alcoholism, which contains no advertising of any kind. Except when the author stops drinking and mentions how hard it is to get a seltzer at a party, I started craving seltzer. I guess this isn't a bad thing--seltzer is pretty cheap--$1.65 for a six-pack, but that's not as cheap as the non-seltzer water that I typically drink, but I'm also kind of digging the carbonation.
Overall, I'm not displeased at this turn of events, just baffled. Going the seltzer route may even save me money in the long run because possibly I'll drink less beer(?) I did invent a frugal cocktail the other day-- the boxed wine spritzer. One part boxed sangria (about $10 for a 5-liter box) to one part some kind of seltzer (I think I used cranberry lime)--fizzy delight in a cup!
So maybe I'm not as impervious to advertising or suggestion as I think, or maybe my body was just really craving carbonation--who knows, but I'll just go with it and see if the mania dies down, or if I become that girl who brings her own seltzer to parties.
