I'm exactly the same at the moment - exhausted from work and not getting any good night's sleep. I make the best progress when I'm not at work.

Also so annoyed that I had to go into work at the weekend yesterday I got to the end of the day and realised that I hadn't thought about LDing once all day or done any RC's. Sometimes real life gets in the way of this.

Having said that I had my first ever lucid moment (that's about all I can call it) last night so not all bad.

Keep up the good work.
