I don't know if you have insomnia, but I had a severe episode recently. I tried everything including powerfull, abyss, somnidgren, neurobalance, zma, mega sleep aid, benedryl, even 2x ambien and nothing worked well. I must say that neurobalance had the most relaxing effect, but I still did not get a deep sleep.
A saliva test confirmed my cortisol was spiking at night. My midnight cortisol was actually higher than morning! My symptoms correlated-- tired all day with more energy at night.
So, I started taking Seriphos (phosphorylated serine) + Relora + Ashwaghanda to reduce cortisol at night and am finally getting some zzz's. Now I can re-try some of those other products. I am also planning to try some Retain2 which suppresses cortisol.
I just thought I'd throw this story in, because if your cortisol rhythm is messed up, you simply can't get a good nights sleep without a potent sedative.
