Reverse bottoming out - doctor's prescription seems absurd; What should I do? (Photo)

I had a major infection on my right implant at 3 days post op so the doctor removed and cleaned the implant via second surgery. The pain and bruises were gone but since then, my right implant didn't stay in place and slid up almost to my collar bone whenever I lied down. I'm 3 months post op now (mentor, 295CC) and the doctor prescribed me to wear a breast band and a certain type of bra for a WHOLE YEAR to fix this problem. This sounds too long and uncomfortable. Is this accurate?
