Then try a mana drink or health energy drink that can be found at http://www.manapotions.com/. I haven't myself tried one yet but that's going to change this weekend. Not only can you order them straight from the site but also at most local Hot Topic stores. They include a search engine on their page to help you find the closest retail place near you that sells them. Go check them out and live your RPG dreams everyday, every time that you need a boost. Besides they just look cool.
