I think the premise is flawed. There is no non autistic version of myself especially as it’s a developmental disorder. So I couldn’t be allistic so much as I could be killed and and replaced with an allistic double. Similarly there’s no reversible procedure. Or at the very least memories formed by the allistic self would be recalled by and processed by my autistic brain so it would be akin to going into a coma and reading a story about this other person who lived in my skin while I was out. I suppose the real trick to make the question worked would be some sort of duality which I think you can tell I don’t believe in.
Cool thought experiment though. Helped me clarify my thinking, which is appreciated.
What I try to do is take care of myself as much as possible, sleep, exercise, etc. so that I can handle the demands. It’s hard and to some extent I think it just always is, my kids have interrupted me plenty as I try and write this. One thing that has helped is having a board where I can stick a yellow or red magnet on when I’m having trouble. I also sometimes use text to let my wife know I’m ok/not mad at her when I don’t want to talk. Your mileage may vary of course. I have a hard time when Im tired but have a pretty good reserve at the beginning of the day.
