Re: GABA question, yes GABA, AGAIN
The only thing I can contribute is that GABA "needs" to cross the BBB to have any effect. GABA by itself doesn't. I don't know anything about succinic semialdehyde, but I would be interested in doing a little bit of research on that.
Picamilon has all the right ingredients for easy cross-over (GABA bonded to niacin), but for me personally, it doesn't seem to work, except perhaps on a minor scale. It's a bit of a shame, since I had high hopes for it.
As for GHB, I know OF it, but I've never taken it, being made illegal in '91 I believe. I don't want to get into the whole Phenibut thing again, but many people have compared it to GHB, or GBL - I forget. But anyway, when Phenibut works, it definitely works, but it certainly isn't for long-term treatment, even less so than benzos.
