Efficacy of Suvorexant on Post-operative Sleep Disturbance

Suvorexant (Belsomra™) is an orexin receptor antagonist that will be administered as 2 tablets (10mg each) for a starting dose of 20mg. If the dose is not well tolerated (e.g., daytime sleepiness), then the dose may be decreased to 10 mg of Suvorexant.

The placebo pill will look identical to Suvorexant and will be taken as 2 tablets.
