I would say enjoy the time before, if you can do the things you won't be able to after. Like having grapefruit, sushi (or anything from where they make sushi or ceviche), meat cooked anything other than medium-well to well done. Also being able to smell flowers. I look at them when I go for my walks, but can't have plants or flowers.
I hope that you are not in too much discomfort. I know I was out of breath with someone else pushing me in a wheel chair even on 6 liters. I wasn't able to complete a sentence without gasping for air. I hope that you don't get as bad as I was before you get your transplant.
