This afternoon, I went to CVS in Keene, NH and bought a few 2-packs of an e-shot called "Extreme Energy 6-Hour Shot". The energy blend includes(believe it or not):theobroma cacao extract(one of the things used in making chocolate) and black pepper extract. I'll try it out tomorrow morning and let you know what I think of whether it is worth the $4.99 per 2-pack or not.
