Yeah, if anything, that book just ingrained in my brain the importantce of not screwing up sleep. So much so that I know have slight fear if I don`t sleep well or need to shorten the sleep for 1-2 days for some reason.
That fear actually really messes with me sometimes. The anxiety of knowing I won’t get enough sleep actually keeps me awake sometimes, then I get more anxious and less likely to sleep, etc...
