well the fake sugars can make you get cravings like that. it does it to some people. plus its not a good thing to have on a fast.
its better and easier to take a bit of juice and add it to water. i really like the V8 splash for this. its super flavorful and makes the water pink. if you are in the mood for fizzy add some to club soda.
maybe doing it that way the fake Sugar
in gum wont bother you.
i think trident and dentene are the easiest to deal with without making hunger. sometimes just the chewing and salvia production can make you hungry....but fat burner breath is BAD. so i totally understand the whole gum for public appearances thing. hee hee
