Wear Cervical Collar, Don't wear Cervical Collar

@ weeks post surgery. Fused c4-c5, c5-c6 used my own hip bone, and titanium plates screwed in. The neurosergeon told me to wear the Miami J brace till I see him again at the end o0f October. That will be 5 weeks post surgery. But the physician's assistant told me yesterday, 2 weeks post-op, that I can start to gradulay begin to stop using the collar. On sites like this one, I read differing opinions. Some say to wear the collar 24/7, and others say with the plate involvement in the fusion, no collar is needed for any length of time.

Does anybody have an opinion about this? The collar is getting very, very old with each passing day!
