jay jay, just go into this place and talk to they guy at the counter. He knows everything about the different types of herbal e's. The one's I tired were called energy bombs-no caffiene or guarana, just chinese herbs! I SWEAR to you they work!!!! I got my friend to have some, she's never had a real e before, but wasn't scared to try the herbal stuff because it's natural. Let me tell you, she had the best night, I've never seen the girl jump around like a kangaroo on the dance floor!!!
