Same here for ADHD people things like caffiene, sugar and so on act as a calming. Basically their brians are "wired" the opposite of the normal, normal people get hyped up and so on from stimulants where as stimulants calm those with ADD and ADHD. That is why Ritalin is so popular and is usually the first medication ADD and ADHD is treated with. it is a stimulant, not a tranquilizer that almost always works.
