And it only gets better from here...
It's the simple things that amaze me. It's wonderful to finally be able to take a deep breath and hold it for more than a couple seconds without choking, and it's great that I can actually taste my food. I'm sure anyone would agree with those; but the simple things that make me smile....walking through the bread aisle at the grocery store. Did it always smell that good? Walking up the road to the mailbox...that's about a quarter mile walk to and from for me, but not only do I make the "journey" without gasping for air, but I can smell the flowers, the grass (just intoxicating after it's freshly mowed), and actually enjoy my view of the mountains while I'm walking, instead of wondering if I'm going to make it back without collapsing.
You've done yourself a wonderful service, and one you won't regret.
