Is it normal to have a stall at 2nd week post surgery. what is your experience like. thanks

Hello all...I am 2 weeks out and I went to the dr the other day for my post-op appt and I told her that the first week I lost 12 lbs and now I am at a stand still. She said not to expect to lose much for another 6-8 weeks because the body is kind of in shock and eventually it will start coming off. My problem is the pain I get when I eat. Makes eating so difficult. I can't get my protein in like this. Does it get better???
