We've discussed this causing heavy/repetitive dreams though. Not good deep REM.
Now that we know that the non RWM sleep is also important, one should not draw any conclusions about it -- other than you need both types.

Fear of sleep making the loop worse. Certainly. I personally find that the more sleep I have, the more I can use...it just gets better.
Not legal but the best for being fresh in the morning.
However, Zolpidem NOT Controlled Release is a life-saver for me. Not approved in CA last Christmas. UK & US okay. Generic $45 /month, but get strong 12.5 and chop it in halves. CRs are good if you can allow about 14 minimum hours. to the throttle.
