That's a nice routine, but the alarm going off sounds to me like pulling out the power cable while the hard drive is defragmenting or while the OS is applying updates.
all depends on the alarm. I took the time to find a gentle one and it's probably why I nap a lot more often now. There's still the danger of it putting my day to a dead stop but quite often it feels like a net good. Also sleep on the floor to help prevent a deep sleep
