I had a last Friday 2/15 . 5 which took me to 7. I was fine all weekend but then Monday I felt like it may be 2 tight. I did protein shakes for 4 days instead of 2 then soft foods for 2 , normal diet now. I have lost 12 lbs since Friday 2/15 . Is it normal to fill to tight not until 2 days after the fill??
