Have you tried valerian extract at high doses (like, an entire box of pills is what does it for me) for lucid dreaming? because it has caused many times in me the most prolonged and intense oneirogenic effects, so strongly so that it feels like, on waking, that one has been on a rollercoaster, and its been a white knuckle ride, because the entire night has either been one long lucid dream, or many many of them, all connected into a continual narrative following on from one another, even waking up intermittently, go back to sleep and back it comes). Probably the most powerful oneirogen I've ever encountered. Although tachyphylaxis occurs within a couple of such doses to this effect, which also declines fast. It can be so...overwhelming...that its almost like DMT for sleeping people.
I don't know which of the compounds present is responsible, or if its synergistic. Since there are alkaloids, terpenoids, things that have GABAa PAM activity (loreclezole binding site, although I haven't yet tried loreclezole so I can't compare, I've never had any other agonist for that binding site either), probable voltage-gated sodium channel modulators and all sorts. Smells like a dead north korean dictator's armpit after being scrubbed with a wedge of stilton cheese and soaked in fermenting piss, but it does have some astonishing effects. I think I might just go for some tonight (valerian that is), after I take my pain meds, chlormethiazole (which I take for seizure prophylaxis) and a dose of nitrazepam to make sure I'm not awoken by the intensity of the lucid dreaming.
As for huperzine-A, I have experience with this as a nootropic. Best to start small (say, 50ug) and build up slowly until you get where you want to be. This is after all, a nerve agent, and it does have the same sorts of dangers as other nerve agents, although unlike organophosphates it can neither be removed from cholinesterase with oximes, nor does it form a complex with the enzyme that ages and undergoes a rearrangement reaction after a time to form an irreversible complex, like organophosphate military nerve agents do. But too large a dose can still poison a person, and going up too far too quickly will make you puke out of arse holes you didn't even know you had, along with sweating, muscle cramping or fasciculations or both, seizure in large overdose, paralysis and inability to breathe if one really overdid it, the hershey squirts, salivation, vomiting, rhinorrhea and a host of other pleasant effects. So going up from initially about 50ug, or 100ug in 25-50ug increments, smaller increments the closer you are to larger dosages is advisable.
