I am addicted to caffeine...not in a bad way, but I have to have my morning coffee, which I put in a thermos cup and drink during my daily morning walk around 6:15 a.m. Nothing like that first sip! Then I have one more cup after my walk.
I have never tried the energy drinks, though. I am kind of afraid of putting that stuff into my body. Therefore, I don't know if they really work.
That being said, I DO drink a bottle of Starbucks coffee and milk mid-afternoon to get me out of my afternoon wind-down lag. It does perk me up, and it is only 110 calories. I think I may be addicted to that afternoon drink, but I love it. And it does work for me.
Great question, blessings, Sparklea
