I just weighed for week number four post op and I only lost .6 pounds for the week. I'm kind of bummed but somebody else told me I was probably still dealing with recovery. Has anyone else had this issue or should I be worried?

Yes. I'm less than 4 weeks out and had a stall already. Make sure you are getting your protein and water. You will hit slow losses and stalls. Know it will happen and push through. I was starting to panic and fret about ít. Try not to. I know, easier said than done
