Liver Transplant and THC

I am 4 months post liver transplant . I also underwent emergency surgery for a complete small bowel obstruction a few weeks ago. I have lost 95 pounds and have zero appetite. My liver docs are saying a feeding tube may be necessary. My question is- does anyone here use THC as an appetite stimulant ? If so did your team approve or recommend it ? Also, has it interfered with Tacro levels at all ? I was prescribed a Delta 9 type of pill but my insurance denied it. Any help with this would be greatly appreciated .
