I too well know your pain...
Right now I am facing a blank corner wall. This is the "living area" and behind me to my right is the television that somebody else watches all evening.
I have a problem with focus - and so I often find myself turning back and forth even when I 'don't' want to. It is not helpful to my energy levels and I do sometimes sleep in this non-comfy chair in the sweltering and humid summer heat.
Music is my only counter - preferably something instrumental and up-beat - no lyrics - like some game music.
I feel that you have the right idea. Moving about is a necessity. I am glad that you are taking action to sort your situation.
Game music?? xD
Yea, I can’t think well and hear lyrics at the same time.
Well game music works for me, not necessarily for you. ;c)
You are probably familiar enough with the Super Mario tune (who isn't?) but sometimes games come out with pretty nice sound tracks. An obscure one is 'Morty on the Run'. Less obscure is anything 'Undertale' related (warning, mileage varies since the fanbase is strong but all over the place. This 4 1/2 minute clip is an OK compressed remix sample).
I personally like most non-brooding instrumental music however. It doesn't get in the way of thinking.
