It's great that your AHI is very low @LadyShadow

I was in bed by 10:20pm last night, but then I read until 11pm. Woke up at 6am intending to do some deep breathing for a few minutes. Woke up at 7am for real and scrambled out of bed and rushed to get ready.

And in that rush, I forgot to take my effexor and nuvigil. At work I started yawning uncontrollably at about 11am. Fortunately it was just about a 10 minute spell, and I managed to get through the day without anyone noticing.

I'm thinking an 8-hour sleep is ideal; 10pm should be my cutoff, like @Tart Cherry Jam.
