omg! I'm 6 weeks post op and I have been dealing with the exact same problem, every second week I have been stalling I didn't know if it was cause I was struggling to have protein, my caloric intake I was worried I wasn't going to get over the stall too.
I'm also eating 800-950 calories a day is that too much 6 weeks out oh and just before a stall I will gain a pound then stall and then I lose 5 pounds then gain a pound and stall is this odd??
