At A Loss

     6 days and I've lost half a pound. I'm not sure what is going on. I lost a pound on Sunday but since then I have gained back a half pound and stopped losing. I'm not cheating, and I even stopped running, thinking that might have been the culprit. I also started drinking more water, but nothing seems to get my weight loss moving. The 30 day mark is coming up and I haven't lost 20 pounds yet. It's just disappointing. I don't know what I'm doing wrong. I keep telling myself that one day I will step on the scale and the number will be different, but it seems like it has been a long enough of a stall to be worried. I am at a loss right now, and not a good loss.
