I had a double lung transplant in 2022 and you can read my story on this site. However, I went to being on 30 liters of oxygen to not needing anything any more. I was pretty much bedridden and then received my lungs. I made sure in the hospital to get up and walk when ever possible. I would walk with anyone. I have pretty much settled into a routine of taking my medication. The meds for the transplant are only twice a day, but other issues have arisen due to taking the meds (or just that they have been noticed now) that I need to take other meds and take meds 6x a day in order to not have bad drug interactions. Life is much better now though. I am able to get up and walk, go swimming (in my pool), cook and take care of my family (instead of them caring for me). Life is not what it was before I got sick, but it is good.
