I was discharged the next day. I had my husband to help at home - which was useful - so yes, have someone there for a few days. No showering the first week for me. Definitely get a shower bench. I was too weak to stand for a week or more. Ok, here is the TMI for some, but might be useful for you: get some personal feminine wipes to use to freshen up each day in your nether regions. ( I would use the proper terms, but don't want to embarrass anyone). It was so nice to be fresh and then I used a hot washcloth to take a birdbath the rest of the body. Having someone use a HOT washcloth on my back was heaven. I bathed every day somehow. It was my routine to feel like I was recovering.
I did not have a sore throat - don't think I was intubated. I had a spinal and a nerve block.
Do not put anything on your incision until the doctor gives you the ok. I used Vitamin E, but now just a good lotion.
I did not use a reacher or a sock thing. My husband helped me put on my slippers each day until I figured out how to hold the back of it with my good leg/foot and slide my operated leg into it. I could reach it enough by then to pull the back of it up.
Your couch may be a problem if you are tall. Some couches are very low. If you find yours is, then just double up the cushions where you will be sitting or add some pillows under the one you sit on to raise it higher. It will be hard to get up from a low seat - unless you are short. I am not.
The bathroom- do you have one of those raised toilet seats? (The plastic ones that you attach) You will definitely either need a grab bar (I installed an 8 inch one vertically to grab on and pull myself up with) or the handles that affix themselves to your toilet. Some people get the 3 in 1 toilet. I totally agree with Celle - go before you really need to. My OS's PA told me to wear panty liners if I didn't think I could make it. A good idea, although I planned ahead. You will want to get up every hour and walk around, so on one of those trips, you can do what I call a "preemptive pee"

At night, have your walker at the ready with a clear path and night lights, so you can get up and make it there easily.
I had friends and neighbors, as well as family stopping in. Many brought food. I enjoyed the break in the monotony. No one stayed too long. It is comforting to have someone with you at first- it can be scary. It is a big surgery and it is painful. Either download you an app for your meds or make a schedule. You want to stay ahead of the pain. Oh - get some Miralax and stool softeners - you will need them. It is well known on the site that the Poop Fairy is a stranger at times.

Also, GET YOUR PRESCRIPTIONS FILLED AT THE HOSPITAL BEFORE DISCHARGE OR GET THEM AHEAD OF TIME. Too many people have had to do without because of a late discharge. My husband had to go to THREE pharmacies to get all the narcotics and pills.
There, as you can see, I am not shy about things and probably gave you more information than you wanted!

You will do fine and be so happy - in a few months....
