I tried the apollo neuro last summer when I was about 13 months post-jump. It didn't do anything for me re: sleep or symptoms, in fact I think it may have aggravated my neuropathy. My understanding is it is supposed to increase the resilience of your autonomic NS, and hence increase heart rate variability and overall well-being.
Separately I got tested for vitamin D status, and was borderline low. I bought a Sperti vitamin D sunlamp (only one on the market for UVB). Although I was getting 6-7 hours of broken sleep (not terrible for jumping from benzos), I noticed a real improvement in my sleep. Now getting 7-9 hours each night, still a few awakenings but I suspect my restorative sleep is much improved. [...], I would suggest getting your Vitamin D checked, as almost EVERYONE is deficient and it is very important for sleep.
Good Luck!
