I find that vaping doesn't curb hunger, but it does curb any cravings for sweets that might arise, (and that's the real problem; carbs).
So instead of having some dessert food, I vape, e.g. Custard's Last Stand, Creme Brulee, Or3o, etc, (all from Nicoticket). This satisfies the sweet tooth and urge for nicotine that both follow a good meal.
