I can say from personal experience I've noticed that when I don't get enough sleep, the next day I'm noticeably more prone to stress, sentences are more difficult to construct, and my memory worsens.

Proper sleep is a very high priority for me these days.

Your last two symptoms definitely resonate with me, with the addition of loss of self control, which I definitely notice while eating.

The first symptom (more prone to stress) seems to have a tipping point with me. If I get between 4-8 hours it is certainly true, but below that I feel considerably less stress, more creativity, and an increase in humor. I'm not sure why.

Same where. When I miss sleep the world becomes a very confusing dark place. Things that should be easy suddenly become difficult and I can get very short tempered.
