Brief Summary:
Available data suggest that obtaining adequate sleep is associated with a better ability of the body to use carbohydrates as a source of energy and a lower risk of developing diabetes. The sleeping pill, Eszopiclone (Lunesta), has been approved by the Food and Drug Administration for the treatment of people who complain of trouble falling or staying asleep. This study will examine the hypothesis that the use of Eszopiclone (Lunesta) to improve the sleep of people with insomnia may also improve the use of sugar in their body.

Condition or disease Intervention/treatment Phase
Sleep Insomnia Insulin Resistance Drug: Eszopiclone Drug: Placebo Phase 4

Detailed Description:
Study participants will complete a set of oral and intravenous glucose (sugar) tolerance tests, which will be performed on two separate occasions in random order: once after a week of treatment with Eszopiclone (Lunesta) and once again after a week of receiving placebo.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 20 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
