I have no idea. It finally stopped, though. Maybe the PB and banana sammich did the trick?
I'm not sure WTF happened. I woke up at 2am with a stomach ache. Thought I was going to barf, so I took a few tums to neutralize the acid. Next thing I know, I'm taking the browns to the superbowl and listening to muddy waters at the same time.
It was followed by several more episodes. I was drinking water, trying to keep up. When it finally stopped, I showered and went back to bed to get the sleep that was interrupted.
I'm hungry as hell now!
