Reading this account, I'm struck by the different ice machine/ice pak camps. Different strokes fer sure, eh? Personally,I wasnt a big fan of the machine…for several reasons. 1) I am long-legged and I often wanted ice for the hurting I had in multiple places; 2) I'm 'afflicted' with multiple get-ups for pit stops thru the night and messing with the hose, etc. tried my patience; 3) after the first few days, I was all on my own and found the hassle of replenishing ice bottles to and from the freezer…well, a hassle.. I had a number of ice paks (my faves are the ones Beachy shows in her post above) from my prior hip surgeries and I relied on those. I could position them simultaneously in the various places that craved some relief (including the BACK of the knee) and there was no drippy mess. Also, I could ice wherever I happened to be settled in the house. I'm in cold country too, so I sympathize with the reluctance to apply cold when you already feel chilled through. Some soft, flannel-y-fabric twixt pak and skin was useful. And, wrapping something warm around your upper self while the lower limbs get the cold plunge treatment.
I think I was one of the lucky ones - no ill effects from the oxy PLUS I found it eased me into gentle sleep. Also helpful for back sleeping was one of those big, sort of semi-easy chair pillows with 'arms' so that I could stay propped up and -major! - a neck pillow, which I use still. Now that I'm 11 weeks out -

hard to believe, I just had to go and check - things are settling in pretty nicely. My chronic insomnia issues kicked back in as I was leaving the drugs. Thanks to my primary, I discovered Trazadone - non-habit forming, etc., good gentle rest, no 'sludgey' hangover. Those of you struggling with insomnia (it is horrible!), I suggest you look into it. I take it only when I sense it's going to be a bad night…def not every night. And I'm finding how life-changing it is to actually be 'well-rested.'
