Hi Justin,
Congrats to you on your weight loss and don't let it get you down if it slows for a bit. You're still early in your post-op journey, and these things happen. Step up some aspect of your diet and/or exercise, and it should get moving faster again.
I read your profile and found it interesting that your friend said you'd changed. My fiance says the same of me, tho I can't see it. Other than the attitude, of course. It's amazing how quickly that adjusts, huh?
Best wishes to you on your weight loss journey!
