Just a note: if you have stairs, climb 'em as part of your recovery. I'm not quite 3 weeks post op today, but went to see my surgeon yesterday and he was amazed at my progress. I'm actually going to have trouble squeezing a few weeks of part-time disability if I keep doing this; they'll want me back full time if I don't watch it. But I've still got 2.5 weeks to go before I have to apply for more, so maybe I won't want it by then.
At any rate, I'm pretty sure that my effort to climb up and down a flight and a half of stairs several times a day after day 3 home has made a big difference with my mobility and stamina. I was out with my daughter yesterday (she took me to the surgeon's appt.) and we hit Starbucks and a half price books before I started to fade. Came home, took a nap, and was up and feeling refreshed after a couple of hours. Chest is still sore, I still tire fairly easily, but I'm off the hydrocodone completely. Doc said I could take ibuprofen if I gave my aspirin time to work on my platelets in the morning (which is good because acetaminophen is not the pain-killer of choice for folks on statins). But so far I haven't needed but one dose, and that was after my "shopping spree."
The advice I was given after my CABG seems to hold here: exercise as frequently as you can without tiring yourself out, even if it's just walking around the house and/or climbing a few stairs.
