I had my strapping taken off after long 9 days last Monday just gone, I managed fine it was difficult mainly at night as hard to take a deep breath but it’s honestly so worth it and I’d say around post op day 2-3 it eased off and my body adapted to the strapping but you will feel tightness and shortness of breath as the strapping squeezes your chest down
Goodluck but in cases where you can’t handle it alot girls have taken them off, but I advise not to as for me well worth it x
