hey i think you can but not to much as it might make you crave something else kinda sweet, i always used to have cinnamon and nutmeg on sweet things, but i am finding if i crave something extra sweet add a tablet sweetner to my shakes for a day or two then the craving goes and i find it ends up too sweet.
anyhowz info that you werent really asking for but hey try it if you like but dont use too much x
