My relationship with coffee and caffeine in general is a love hate relationship. Well, not really. It is more of love and love and more love, but other people say he is no good for me. I am just going to say this bluntly. I am addicted to caffeine, and I'm 16. I think I have a problem. My main issue is with coffee. I have writers block, so here are pictures related to my caffeine/coffee things. I also love Red Bull. I had the 20 ounce size a few days ago. Here is the amount of caffeine in this stuff 80 mg/250 ml. I did the math (probably not correct) and that is about 193 mg of caffeine in my one 20 ounce can of Red Bull. I am pathetic.
