How soon after BBL can I sit fulltime without hurting my graft... like 5 hrs Straight?

My patients leave the operating room sitting on their back. I find hard to instruct patients to lay otherwise. However, you have to exercise your judgement and consult with your surgeon.Generally, I let my patients drive freely in 2 weeks and resume unrestricted activity in 4 weeks. I tell my patients to discard the garment at 6 weeks and to expect their result from 12 weeks onwards.

I would avoid sitting as much as possible for the first 2 to 3 weeks following a Brazilian butt lift.  At three weeks it should be safe to sit for several hours.  However, I would suggest you get up and move around every hour or two.  If you are still wearing a compression garment be certain to straighten it out when you get up.  Best wishes.
