I get very disoriented with coffee and chocolate -- loss of balance and dizziness (maybe migraine related). So I get my caffeine from tea. I like to mix my teas together. I usually mix black tea, green tea, blueberry tea, and acai berry tea. I boil them together in a huge pot and then fill an empty juice bottle with the tea and refrigerate it. The tea does wonders for me especially when I feel the pyridostigmine wearing off and it tastes really good.
