hi
what exactly do you crave? is it sugar or carbohydrates? there's some book called sugar busters that goes into it.
What about your diet? if you're comfortable with the change, it shouldn't feel like a diet - it should just feel natural, I think. i switched, for example to decaff tea and low sugar tecconi herbal coffee - i like it so much i don't even miss coffee - what exactly for example led you to eat at mcdonalds (i can easily avoid it since i got food poisioning there twice
)
