Weight Fluctuation

So I was super excited on Monday because I got my weight down to the one hundred and twenties. Ya 129.9 is way too close to 130 but I didn't care. I was still really excited. But then on Tuesday I got frustrated because I was back up to 131.4. So I googled weight fluctuation to see why this happens because I have noticed it a lot. I read this really good article.

After thinking about it I feel better now. I was fluctuating between 131 and 134 and now I am fluctuating between 129 and 131. I say that is progress :)
