As of late, I am addicted to the following:
Watered down muscle milk with tons of ice in it... (my mom bought a gigantic box for me one time at Costco to make my muscles grow even bigger than they already are. but sadly, my box is almost gone ... uhh mom are you reading this??...)
Diet hot chocolate with lots of ice in it... so it's basically ends up being cold chocolate...
Strange... but delicious... it hits the spot on these hot summer days. ( and it is low cal)
