Am I doing something wrong?

Had RNY on 4/26/10 - I feel great have dropped 2 1/2 clothes sizes and have tons more energy BUT only 55 lbs. have disappeared.  I lose 3 - 5 lbs and then I stall for up to 3 weeks.  I am paying close attention to what I am eating and eat very little.  Taking my vitamins, protein and drinking fluids.  I walk almost everyday for at least 20 - 40 minutes. Maybe I am just a slow loser?  Just getting a little concerned and wondering if I am the only one.  Thanks

It could also be how much you have to lose, if not that much, you will lose slower. But 55 lbs seems good to me.

Thanks Emily,
