I think it's good to examine all habits that we have, and if this article gets you to consider the (potentially unknown) trade offs you're making, great!
but to really know what they are, RCT self-experiments are the best way to work out what's really going on.
gwern has a bunch of examples (https://gwern.net/zeo/caffeine) but you should tailor yours to the effects you're most interested in.
incidentally, does anyone here have a go-to tutorial for how to set one up, how to do power analysis, etc? i'm persuaded by why we should do RCTs, but I don't have the background in statistics to confidently run them myself.
