How often does this hyperfocus thing happen to you all? It is definitely a stress related thing for me, but it is even just mild things like…well lets just says it would not have any sort of life altering consequence. Its not so much of what I have not finished it is what needs to be completed. It is amazing what you do get done when you dont sleep, 
and it is also amazing the trail of destruction left behind. However, when I crash….boy do I crash. The thing is I will sleep for the most wonderful 8-10hrs ever and I am good to go. It is not uncommon for me to do 36-48 sprints at least every 1.5 to 2 weeks.
Most sleeping aids I have tried are hallucinogenic or they make me completely nonfunctional for no less than two days. I find it enjoyable to read, so that is often effective.
I guess it would just make me feel better knowing that I am not alone in the frequency portion of this. Someone could at least lie and say yes. …kidding.
