Hmm, when I&#x27;m very tired I get slight tingling sensations in my feet sometimes. I wonder if that is (anecdotally of course) related to the insulin sensitivity. I&#x27;ve heard that is a symptom of diabetes.<p>Usually sleep fixes everything right back up. I&#x27;m pretty skinny, although I know that&#x27;s not necessarily always an indicator of good health, I&#x27;m <i>pretty</i> sure I&#x27;m <i>pretty</i> healthy.
