Hang in there JS. You guys have so much on your plates! Good to hear he is driving now, that sounds like a positive sign, no? But too bad he feels the need to smoke, that certainly does not help him. But as you say, addictions can be pernicious little devils. As time goes on he should get more strength as he recovers more from the open heart surgery. It does take time though, that is invasive surgery!

I am not familiar with "hydro" for a furnace? It sounds like it's something you need to buy and have on hand to start it? Sorry, this is a new one on me, but if it's something you could run out of then that is certainly a worry. Hope you are able to remain stocked up with it. Best to you and your husband, Hank
