Got it from my sister and nephews over Thanksgiving. It didn't hit me until early hours Monday morning. Woke up to my stomach making noises out of this world. I just laid there waiting for it to "happen"... Well it happened, proceeded to keep happening. When i wasn't throwing up or on the throne, I was sleeping. Tried working yesterday, I couldn't. I work in construction and work out 6 times a week, and most of the time its twice a day. I'm far from the worlds strongest man, but I can swing 20lbs sledgehammers with one arm, yesterday i couldn't even swing a pickaxe trying to break through the frost on the ground. This thing kicked the crap out of me. I'm just grateful I got the bug, instead of grandma, or other older people we celebrated Thanksgiving with.
