I can definately relate. I went on little to no sleep every night for around 11 months one time. I just didnt need the sleep. I would get around 45 minutes a night sometimes none but I would make myself lay down atleast. The schedule or tight routine definately works for me. I was the most stable when I had one. I dont have one now but I am working on making a new one as I dont work or have my girls everyday anymore.
A couple weeks every year I get the mental exhaustion and will almost sleep around the clock for a while. Its like my brains catching up from the sleeplessness I go through most of the year.
