Brick, take the drugs if you need them. It hurts to breath deeply, which is what you need to do the keep the pnumonia far away!
Did they harvest any veins from your legs, or did they use either of the 2 IMA's? (The arteries behind your sternum)
Keep positive thoughts, regardless how you feel! Concentrate on how great it will feel to walk around your own 'hood!
Be mindful of any therapy, they are there to help you....and, it works!
