8 Days Post Op Gastric Bypass Noticing a Difference-First NSV

My size 18's are falling off of me and people keep telling me my face is smaller. I guess I'm officially in a 16 now. Going to pick up a few pairs of cheap pants tomorrow to get me through lol.I have lost ten lbs since surgery and am feeling extra tired lately. I went to Dunkin Donuts with my hunnie today and asked them to warm up my 1/3 cup of cream of broccoli soup in their microwave lol. It was nice to feel a small sense of normalcy return. I also think I have an NSV but hoping it's not a fluke. For as long as I can remember when I sit for any amount of time my lower back is stiff and sore when I stand up. Today it hasn't been. I was so surprised when I realized it that I sat down and stood back up again!!!! Once again I am feeling so very grateful that I had the opportunity to have this surgery!!!! GRATITUDE in abundance!
