I am so addicted to those. When I started working at this office I was ecstatic because it was really hot and there's a starbucks around the corner. :) :) :) :) Then the sugar started to make me sleepy by the end of the day and now they're only a treat to make me feel good when I'm having a bad day.
same here, you get so wired for like a few hours then you crash the ugliest crash ever! happens to me all the time! lol
