This study investigates the effect of exenatide, a FDA approved medication for the treatment of type 2 diabetes on sleep duration and quality. Individuals with type 2 diabetes will be studied before and during treatment with Exenatide.

Enrolled individuals will be asked to come to the University of Chicago for 3-4 outpatient visits over the course of 3-4 months.

Inclusion Criteria:

Patients taking diabetes medications other then insulin will be included, but changes to their medications may be made as deemed necessary by their physician. Patients on stable medications for chronic and co-morbid conditions (high blood pressure, high cholesterol, etc) will be eligible

Exclusion Criteria:

Patients with moderate or severe kidney disease and history of pancreatitis or patients on insulin will be excluded, as Exenatide use is contraindicated or risky in these conditions.

Patients with unstable cardiac, neurological or psychiatric disease and women who are pregnant or trying to get pregnant will be excluded. Patients who have severe COPD, severe neuropathy or chronic pain, which could impair sleep, will be excluded. Shift workers will be also excluded.
