This is interesting. There are somewhat similar sentiments among anarchists in the US who think “burning it all down” is the only way to fix the system (rebuilding it from the ashes). In their fantasy, it’s worth it to them to just destroy any and all parts of the current system and spread fear and chaos. Not the same idea, but I can see some overlap in mentality.
I believe age and exercise are two important factors here. Older people tend to function okay on less sleep. Regular exercise helps with both regular sleep and sleep schedule adjustments. If you can, try to put in more exercise for a few days after the switch. Hopefully it helps.
