I'm coming to grips with it....I'm addicted to caffeine. Seriously though, I'm no nutrionist, but from what I hear , overuse can make you irritable, grumpy,etc.... Well , I have had terrible mood swings and temper tantrums to many times these days. So I'm gonna try to kick caffeine , if I can..... I love the taste of soda though.....GRRRR!!! Any help?
