I am a first grade teacher. Had revision band to sleeve on 7/28/15. Went back to in service on 8/7. Students came 8/12. In service wasn't too bad, first 3 days of school were rough, but made it. Yesterday, Monday 8/17, felt best ever. Wish I had waited 3 weeks instead of two, but like you hated to miss the days. Today I am tired, but not extraordinarily so. Haven't weighed since my one week post op visit where I had lost almost 20 lb. since surgery. Started at 277, weighed 258 at 1 week checkup.
