This was in my snack parcel I got from the America's a good time ago - it contained the coke and lots of other little bits. This I'd been saving for a special time when I was at work, stuck and starving. One morning this occurred at about 11ish and I devoured the bar before heading to the 12 O'clock meeting.
This wasn't really a short term mistake, the bar is basically an American Toffee crisp - but longer. There is also an important difference in the sheer amount of mind bending chemicals that are hiding in here. I was slightly hyperactive for the whole day! I had to continually check that I wasn't just randomly talking out loud and over reacting to the situations. I also had to force myself to sit down and carry on with things. Hyperactive energy is great to funnel into work though so I got a lot done.
I think that the small Reese's things are fine as I only eat one from the pack per snack attack, but finishing all of this at once was probably a bit much.
