It sounds like you're well on your way to some serious weight loss, and like Nanci said, the effects are completely temporary. If you rest a few days and stick to the diet, you should lose that 1.8 pounds and a little more. Then again... you have a new bike... better to ride it as often as possible and just deal with the water weight! :D
Good luck with the weight loss, and 'gratz on the new bike!
