So I was tempted over to the "dark side" and got myself some 4mg G + 200mg Ch Bitartrate capsules, and tried one for the first time last night.
I got to sleep a bit late - about midnight, which was probably a mistake in retrospect, but then woke naturally at about 3am and took the tablet.
I was trying to follow Yuschak's process for this, so did a WBTB WILD technique that started on my back for about 1/2 hour, then on to my side and just passively wait for the enhnced imagery to form a lucid.
But... it didn't quite work like that. After about 1/2 hour I did start to feel something was happening, but there was nothing earth-shattering. Once on my side I waited, and waited, and just found it difficult to get back to sleep. Then at about 5 am, maybe preceded with a bit of non-REM sleep, I woke and suddenly had a very wierd almost violent lucid experience. It was almost as if the bedclothes were swirling around, with me inside being spun about and thrown out towards the wall. I knew it was a dream, and it was super vivid in touch sound and vision, but only lasted a few seconds. It was so shockingly quick and violent (not painful, but just really strong) that it woke me fully. I wasn't frightened by it at all.
Then I went on, probably in dream cycles, to have some more very vivid dreams, including one more lucid, which again only lasted a few seconds before I woke.
So some success because that's the first time I have had 2 lucids in a night.
The next morning, although I had not got a great night's sleep, I felt pretty good. Not "really buzzing great" or anything like that, but just "normal good sleep" good.
During the day today I have not felt any different (except for the memories of the short lucid experiences).

I've resolved to only do this once a week to start with to ensure no chance of desensitisation.
