christina, it happens a LOT - type in the search button above "stall" or "plateau". I know I went into a panic and wrote on there too searching for answers, and I know I wasn't eating too much! I think most of us stall anytime after about the 3 week mark. I went up as well some days, but over time and on the whole, generally it has to go down. Make sure you are keeping up your protein and fliud intake, and check out the other sites on stalls. I got so upset I wanted to give up and binge - lucky I had the sleeve, it stopped me doing what I always used to do, and then I started to lose again!
