Do I have to stop taking Tramadol (200 mg a day) prior to surgery? If so, how long?

I take 200 mg of Tramadol that totally controls pain that I have associated with lumbar spinal fusion in 2000. Don't think I can stop taking that for long periods before surgery. I get different answers from the doctors I've talked to - most say it isn't a problem but 2 doctors want me to stop that med for up to 4 weeks before which pretty much rules out a facelift. I wouldn't take the Tramadol if I didn't need it. I'm 62 and in good health otherwise with good BP, use treadmill 4 times a week.
