Stall at 7 weeks post op

I'm 7 weeks post op and I seem to have hit a stall. I lost good for the first 3 to 4 weeks, now I'm bouncing back and forth between 270 and 268. I was 295. I did add exercise,I walk about 1/2 mile and do a little strength training, like 10 sets of 3 using 35 lb weights. Any suggestions would be appreciated.

 I'm at 8 weeks out and I did the same thing at about 6-7 weeks.

I thought "oh no, can I fail at THIS too?!"  

But then I decided to ignore that bout of low self-esteem, and to refocus on eating right, getting more fluids and sleep, and waiting it out. Then it seemed like overnight, things just shifted again. I think our bodies will do this, and the key will be to just ride it out. Don't panic!
 
For me, I'm staying off the scale except for once a week at most. The daily loss is not so great now, and it feels defeating if there is no movement. Work your program one day at a time, and get plenty of fluids, rest and protein. Exercise moderately and have fun - enjoy the process and the NSVs.

Hang in there!!

 Thank you :) I'm going back to MEASURING everything and staying away from high carb foods.

I know what I'm doing wrong at 3 months out.
I'm having a lot of pain due to sciatica...not related to RNY surgery.
I need to get back on track.  I think I've been eating 3 larger meals...instead of spreading it out over 5 or 6 eating episodes.
But the pain is an excuse.  I have to grin and bear it until it passes.
I'm confident that it will.

 Not sure if it works, but some on the board have tried to up the protein intake and the water to see if it breaks your stall.
