Study Arms:
- Control (Type: PLACEBO_COMPARATOR): Placebo capsules will be prepared with opaque gelatin capsules, filled using methylcellulose and over-encapsulated to appear identical to interventional drug. Placebo capsules will be given orally in the same regimen as intervention (three times daily for 14 days). Capsules will be prepared by the research pharmacist and will be mailed to study subjects directly by courier. Placebo capsules will be stored at room temperature.
- Melatonin (Type: EXPERIMENTAL): Melatonin will be administered orally as a 10 mg dose three times a day for 14 days. Size 4 clear vegetable cellulose capsules containing 10 mg melatonin, microcrystalline cellulose, and rice concentrate prepared by Life Extension® will be over-encapsulated in opaque gelatin capsules. Over-encapsulation of melatonin treatments will be done by the research pharmacist and will be mailed to study subjects directly by courier. Melatonin capsules will be stored at room temperature.

Based on this trial design, predict the completion outcome and termination type (if applicable).
