Normal to sleep 11-12 hours, only on work days?
I work in IT as a consultant, have been doing this for the last 7 years. I'm struggling to keep up these days, constantly inundated with difficult work, and I find myself sleeping upwards of 11 hours, sometimes more, if I don't set an alarm for the morning. However, this issue subsides after about a week of vacation, after which I return to an 8-hour cycle. The problem quickly worsens again when I go back to work. Is this normal? Or should I find a new job?
