Correlation between sleep quantity : quality and diet that day

[HealingCalmingSoothing]

Has anybody else noticed this correlation?

I am really strict with my diet most of the time but will occasionally have a blow out. I've noticed that when I eat in excess of my normal diet, I sleep way way more that evening.

I'm almost the opposite in that what I eat doesn't seem to affect my sleep, but my quantity of sleep affects the quality of what I eat. When DS is teething or just not sleeping well I crave carbs and sugar
