I had an organ transplant 4 years ago and have been on medication ever since, and likely will be for the rest of my life.

Is there any way around this? Any new technology or medication being worked on that I don't have to take what I'm taking now? I don't mind taking pills but it weakens my immune system, given me terrible acne, I have to avoid too much sun exposure, and I'm even having minor memory issues. Is there a way to trick my organ to think it's my own? I just want this to end.
