Just an FYI - there are supplements recommended above that contain Magnesium, which is known to benefit sleep, but also to promote diarrhea (think Milk of Magnesia if you’re old enough to remember that).
I used CBD on a daily basis for a while and while I felt like it worked, after getting tired of the expense I cut it out, and now I’m not sure if it did over the long haul. Almost like i had developed some resistence to it. I now only take it when I’ve had a few nights of poor sleep or after a big ride day, and it does seem to help. I’m very skeptical of anything that depends on me “thinking it worked” though, so ymmv.
I find THC and Ambien both help me to fall asleep quickly and stay asleep longer, but I get almost no deep sleep from them and don’t actually feel refreshed in the mornings.
Also of note, you can overdo it with Ambien and have bad side effects. I have a friend who took more than prescribed in an airport and woke up several hours later at the end of the flight and had no recollection of ever boarding the plane. Stick to the prescription amount.
I’m very interested in this topic. I live where it’s hot most of the year and find that my best sleep tends to come on vacations where it’s cold or in cold hotel rooms. I just can’t afford to keep my house that cold (financially, and also, my wife gets cold any time the temp gets below 75 or so and I value my marriage!)
