highly favourable snack=)

I used to had it in my tuition classes to keep me from falling asleep.why oh why am i reminiscing all these silly things?this thing sometime appeared to me as an astonishment. I received it again the other day. So, should i keep it or consume it because i seldom buy it now as it's far more expensive in KL..hahaha..i think i'll eat it when im about to fall asleep in class..on top of that thanks for the unexpected Rockies ..
