Day 22...I decided to really go out on a limb for this one, and purchased some apple juice concentrate. When I opened it, regret immediately set in! It resembled some type of apple juice slushy that someone had poured massive amounts of syrup into. But, I made it this far, so I had to go ahead and see how it tasted. I knew if I took it slowly I would never find the courage to take in enough for the brain freeze, so I just threw caution to the wind, gave it my hardest squeeze and shot the concentrated apple juice product in! The effect was instantaneous. I was immediately struck by just how strong the taste of apple juice was, coupled with the extreme cold since it was truly frozen. But, the greatest effect was the substantial amount of concentrate that somehow found its way up my nose, giving me the rare, and completely unintentional, nasal brain freeze. That's right...I journey in the world of brain freezes where no one has gone before!
