Can I poke your diet brain about sugar? I was told I need to cut out sugar and gluten (therapist said cut out completely, I'm slowly weaning because I'm a big sugar/gluten addict) and I can't think of anything I can eat without sugar! I swear it seems like every freaking thing in the store has sugar and I'm stuck

I normally have a bowl of cereal for breakfast (Frosted Flakes or Cheerios), then a sandwich (gluten), crackers (gluten) and yogurt (sugar) for lunch, and some sort of pasta thing (gluten, gluten, sugar in tomato sauce?) for dinner.
Help

(Other people help too, I know Ang is doing the insanity thing and has little knowledge of foods
