Despite what seems like constant changes to the McDonald's menu, somehow they have not found a food product that I choose to eat. Sure...I have kids...so I end up driving through for a meal or two, but not for me. Imagine my surprise when I did give in one day and tried the Strawberry Banana smoothie, and actually really liked it! Thus, I had it on my list to check off as I went through this 31 day challenge! Much like a slushy, the brain freeze here is easy to accomplish because the use of straw shoves the cold directly on the roof of your mouth. This causes the sphenopalatine ganglioneuralgia...or as it is otherwise known...the Brain Freeze!
