  I'm now experiencing the feast part of my sleep cycle. Although there were intermittent interruptions, yesterday i woke up at two, went back to sleep at five, woke up at one, woke up at three, and here i am now at 8.30am. The day before was similar. I think the the fibro pills are the culprit; see i figure it's pointless to go through the feast if it doesn't make me any more energetic. I'd just as soon get four, since i feel pretty much the same anyways.
