Something that worked for me, and allowed me to reduce my sleep by almost an hour was Germanium Sesquioxide
Regarding Germanium... did a quick search. Appears that its import is illegal. Lots of benefits, very rare, declared to be a dangerous substance? You can only find it now in very small portions..like 35mg instead of 500mg. Where do you buy your Germanium?

How are your results with hemi-sync tapes? I think you've mentioned either here or on bwgen that you tried them.

That’s my current project. I have TimeOut for Sleep, where you can essentially program which stages of sleep you go through and in what order and length. I also have SuperSleep, which, to my frustration, I have discovered does not really decrease sleep need. It’s not deep enough. It’s incredibly healing though. I asked what I was listening too and they said it was at or around regular NREM-IV sleep--3ish hz. Just slightly lower. This is a great CD to catch up on sleep debt and heal illness..horrible for sleep reduction though. Again, same with TimeOut for sleep. That CD, though, has a 7 minute REM segment which I find fascinating. All in all, it’s just really cool to be able to program your sleep on a WinAmp Playlist! Amazing what you can do these days
