It made me discover how much stuff has added sugar. Things that I would assume would be fine to eat all had added sugar. Most bread was a write off, practically every sauce, and more or less every packaged food contained sugar.
To be honest, the sugar cravings weren't hard to work through, I've never really eaten much sugar, but the sheer amount of food that I wasn't able to eat because of added sugar was staggering.
At least drinking was easy, I could still drink most wines, beers, and spirits.
