It must of had a lot of sodium. I'm up 2.5 pounds today :P I know it's just water weight if it comes on that fast, still a nasty shock to wake up too. It probably had more to do with the pork rinds dessert I ate late last night as a treat for skipping the desserts at the resteraunt. At least I know I'm still in ketosis, I have the nastiest metal taste in my mouth water just isn't flushing away, blah. Maybe eggs will get rid of it.
