I sometimes feel deprived a lot, but then I plan and think it is okay to have a day off like once a month, if my numbers are otherwise well controlled... so at that day eat all I like of all the forbidden fruits and other wonderfull foods like bread and grains... have a day of once in a while but not too often...is my suggestion, and try to broaden your repetoire of foods and recipees even though you mention that you are aware of the excistence of good recipees , but there must be some that could talk to your tastebuds...
