Why do aspartame-sweetened diet sodas have more "zing" than those sweetened with Splenda?

Question

..or is this just my imagination? (i avoid aspartame sodas, like Diet Pepsi, ....it feels really good to drink it, it gives quite a perk, but afterwards get a nasty headache).....so i stick with Splenda sweetened sodas, like Diet Rite. Do the aspartame drinks have more caffeine or what?

Answer 1

They do not, but they lower metabolism, and stimulate hypothalmus. They make you feel like your body needs more energy-hence the headache.
