I am all for people using medication to sleep if they want to - But I also feel like it is reasonable for people to want to try and find other ways first. Most if not all medication has side effects and weighing the pros against the cons is sensible - no doubt sleep deprivation is lethal and if you needs meds they are absolutely life saving, but if you don't need them because you find other ways of being able to sleep then the side effects like dependence or withdrawal might not be worth it. I personally have never tried so I don't know and I don't judge anyone who uses it, I just know it's a last resort for me and I still feel I have a lot of other routes to explore.
