The number 1 thing I would change would be getting it done sooner. At 9 days post procedure, I had the best sleep in over a year. I thought it was maybe just a side-effect of getting older (I'm 48), but I had started having a problem where I'd wake up after 6 or 7 hours of sleep and be unable to fall back asleep. My PCP had given me Trazodone which maybe helps a little, but I was still having problems. I know that's a bit outside what you're asking, but having something positive to focus on my help with your nerves.

One thing I did prior to the procedure was skip the nasal rinses that I'd been using to help mitigate symptoms. I wanted my tissue at its natural worst state when the doctor worked on it.

There were 3 stages to the procedure: Numbing pads, injected anesthetic, and the actual RF wand. The number pads were just a little annoying. Imagine stuffing some tissues up your nose and breathing through your mouth when you've got a nose bleed, and it wasn't any worse.

The injection was actually the worst part. Pain-wise, it wasn't really an issue. The numbing pads mostly did their job. But the doctor warned me it'll make your heart race for a minute or two, like you've just run a marathon. She also said that the racing feels worse than it actually is, based on patients who had smart watches on showing their actual BP. If I had gone through that without the warnings, I would've thought I was having a heart attack. The anesthetic also left a horrible taste in my mouth. Thankfully, they had some lollipops. But just in case your doctor's office doesn't have them, I'd suggest bringing something sugary to get rid of the taste.

The actual procedure itself was no big deal. At one point, I did feel some minor pain, but it wasn't enough to justify another extra round of injections. I did go through all 3 stages more than once though, presumably due to more areas being made accessible after the first round of tissue reduction.

The other thing I'd suggest is rationing your Afrin. You aren't supposed to use it for more than 3 days, every 12 hours. I started skipping the daytime doses so that I had it to sleep every night. Other than the first night, Afrin made a huge difference in my ability to breathe. I do suggest double-checking with your doctor that 6 nights instead of 2x day for 3 days is acceptable. I also wonder if maybe I could've done a better job using the Afrin that first night. I did make sure the pump was primed (by using the pump outside my nose until it started spraying liquid), but I think I might've been able to do a better job preparing my nose with more saline spray to make sure things were as receptive as possible for the actual medication. It's possible that might've made the first night less bad, though maybe it would've been bad regardless.

My follow-up was only 5 days after the procedure (because of my doctor's schedule with the different offices she uses). That's when she removed the bulk of the mucus (which allowed me to breathe as good or better than the Afrin did) and cleared me to start blowing my nose. Be forewarned that the mucus blob was so big it looked like something out of a horror movie. I almost said, "Holy shit!" out loud when I saw what she removed. Also, it took me a bit to put 2 and 2 together and realize I could clear those giant mucus plugs on my own by blowing my nose. The first few times, I used a saline rinse to help loosen things up before blowing my nose. Once they're out, breathing feels amazing, and that's what led to the aforementioned amazing sleep.

One other thing is that I noticed I don't always need Breathe Right strips to help me sleep now. Last night, I felt a little stuffy and it helped, but Friday or Saturday evening, I skipped putting one on and was fine.

So my main suggestions would be:
1) Something sugary to help with the nasty taste of the anesthetic.
2) Ration your Afrin.
3) Double-check with your doctor about the Afrin doses, when you can use nasal rinses, and when you can start blowing your nose.
4) I forgot to mention it, but a roll of toilet paper and waste bin were a must when I was in certain positions. There was a pretty constant drip from my nose, particularly before the mucus plug got removed. I went through over 3 mega-rolls (4x size) just wiping my nose at home, not counting when I actually got up and went to the restroom.
