Study Summary

The purpose of this study is to test the effects of sleep and eszopiclone, a drug that helps people sleep, on how the body processes glucose (sugar). Eszopiclone is approved by the U.S. Food and Drug Administration (FDA) for sale for the treatment of insomnia. It is marketed in the United States as LUNESTA. Main Hypothesis: Primary insomnia is associated with impairments of glucose metabolism that can be reversed by two months of eszopiclone for the primary insomnia

Primary Outcome

Difference in glucose tolerance (Kg) in response to insulin-modified intravenous glucose tolerance test. Glucose tolerance was calculated as the slope of the natural log of declining glucose values from minute 5 to minute 19 post-infusion. By convention, this negative slope is multiplied by -1, in other words, expressed as a rate of disposal.
