Well it's only been about 24 hours so I can't really say much, but so far so good lol. I drove to Toronto and back without dying so I'm fine at the moment.
And I've heard conflicting theories. One is that your sleep with be 100% REM, another is than it will be mostly REM with a drastically decreased amount of NREM. Either way, it's not that I'll have more REM sleep than I do now, it's just a higher percent will be REM.
