lowering sugar in diet

I am trying to reduce the amount of sugar in my diet for GI reasons. However, I am hitting well over 70 grams per day. This amount is from natural sources, mostly fruits, milk (products like greek yogurt, and 1 c of milk in the morning w my protein shake), my already low sugar cereal (mesa sunrise, goodfriends, etc. that doesn't have any added sugar, just the natural grains). Please do not suggest that I cut out sweets or soda. I do not drink soda, and I limit desserts as much as is reasonable (a girl has to have some chocolate once in a while. I am not including this added sugar in my problem 70 g).

I'm looking for some guidance from people that have been able to reduce their sugar successfully and how they make substitutions. I am a vegetarian, please do not suggest meat.
