I’m sorry that I can’t offer experience but you have gotten some great ideas already. By the time I had come back around I had been out of work for… about a year, but when I was in an office prior to that, I was able to have a small speaker or headphones, could you listen to a podcast or an audible book? & we had an essential oil diffuser so I can second that idea 
now I have one in my bedroom & one in my living room 
Maybe some battery-operated or an app for candles & small crystals to keep in your workspace?
