We've probably discussed this before but there are other much more safe alternative imo: magnesium, melatonin (cycled), Valerian (works in some guys) and some of the anti-stress herbs (rhodiola and ashwagandha) for example. Zinc can help some men.
Can't remember what you said, but you may be high cortisol in the evening. It is quite common for high evening cortisol to keep a guy up. If you haven't checked, it might be wise. Some phosphatidylserine can knock that down in the short term and PMR/meditation in the long term if that is the case. But that's going to be a heck of a lot more safe over the years than Ambien or a pharmaceutical solution.
Man, Peak, your like an Encyclopedia of men's health knowledge!!
I've tried magnesium, melatonin, valerian root, and zinc previously - and they didn't seem to work. Haven't tried the others though. Again, my issue isn't falling asleep, it's getting back to sleep after waking up (generally to take a leak, although that's been a challenge lately as I have to wait for the wood to subside).
I guess Ambien has a short half life, so I can take it at 2am and it wears off by breakfast time. I seem to go in cycles, a few weeks with good sleep, then a few weeks with only 3 hours per night (unless I resort to the Ambien). I'll look into the herbs and phosphatidylserine, thanks for pointing them out. I'm determined to get rid of the Ambien.
