This post hits too close to home. I suffered through this and was the worst during my Masters. I wrote my masters thesis in about two sleepless days. It was the worst period in my life.

I was alarmed, so I went to a psychiatrist and diagnosed me as ADHD, and the stimulants worked wonderfully until I started feeling the long term effects : chronic dry mouth leading me to losing one teeth, insufferable tiredness when not on my meds, and many other to mention.

Recently, my mother has being going trough chemo, and one night when she wasn't using her supplemental oxygen I put it on and went to sleep. In the morning I was my old self.

Went to a sleep center and realized that it was sleep apnea all along decreasing my motivation, my will to do things, my libido. I felt like a 70 year old in the body of a 30 year old.

Such a simple, drug-free solution to my life's woes.

Just putting it out there.
