Maybe for you or maybe not, but I need to write this out there: My wife (42 YO) started to experience sleep issues around a year ago. She tried with lots of stuff including delayed-release Melatonin, and nothing quite worked well. Until she started taking ZMA pills [1]. This supplement really solved her issues. I take "half dose" sporadically and really helps me get a full good deep night sleep.

It may or may not work for you, but it's one of those things that may be worth try it, and they sell it GNC and similar mainstreet stores.

Sure, but something formulated as a profound energy stimulant containing the equivalent of a cup of coffee of caffeine plus other energy boosters could be rightly suspected of affecting energy levels, and so possibly also sleep, given two per day?

Sleep naturally degrades as we age. So potentially the "development" is less a result of doing or not doing something versus just the degradation of sleep as a natural part of the aging process.

Because unfortunately, your problem as you get older is baggage - the worst thief of sleep of all time. Sorry, no cure unless you're a zen stoic psychopath. Would love to achieve that designation myself.
