Maybe block on your router and save your router password such that you need to jump through several hoops to unlock it, eg password saved in one password manager DB whose master password is in another DB whose password is in another DB, etc. If you have to unlock like 10 password databases to get into your router, you’ll probably give up on whatever bad habit you were trying to do as it’s too much effort.

















I’ve never daily driven it as my main machine but I’ve used it as an auxiliary driver for a more high-security machine. Afaik things like gaming are sort of a no-go on Qubes still.
Qubes does not just do sandboxing. It runs all user programs in VMs, which adds non-negligible overhead and makes it an unsuitable OS for many more lightweight systems like laptops. And even if your PC can run Qubes without issue, you may not want that additional overhead if you want to do anything computationally intensive.
