When I was in the AF, I found out this little goody. A friend and I picked up the habit of smoking swisher sweets. One night there was no Coke, just Pepsi. We downed it after smoking a Perfecto, and it made our mouths tingle, not unlike pop rocks. It was then that I switched to Pepsi.
It never did that with other sodas, just pepsi. Any one have any ideas why?
