@TwoKneeOrNotTwoKnee, love your name!!

Although I had my knees done six weeks apart, l, too had a BOGO! Since I had already met my deductible, my second one was free! Gotta love that! For my TKR's I had an epidural with "happy juice." I was a little nervous about it, but it was awesome. Didn't remember a thing, and no nausea afterwards. I've had trouble with nausea after general anesthesia in the past and was glad there was one less thing to worry about.
Although I had one done at a time, my ice machine was my best friend. Since most pain meds have no affect on me, I think the ice helped me more than anything. Another thing to consider (and something I discovered reading here and never would have thought of it) was getting a toilet seat riser. I use Walgreens pharmacy (not sure if you have them by you) and am in their points program. I went online to order the riser and used my points and got it virtually for free! Also, my town has a "nurse's closet" where you can borrow medical equipment for free. I was able to get a cane to use for both knees. (This post makes me look like a cheapskate! But hey, free is my favorite four-letter word!)
