Brief Summary:
The goal of this double-blind clinical trial is to further explore if, how, and for whom orexin antagonism modifies brain-behavior stress targets in moderate to severe alcohol use disorder (AUD). The main questions it aims to answer are:
* Does an acute dose of suvorexant (SUV) and/or daily use of SUV modify brain-behavior targets of AUD dysfunction?
* Does daily SUV use change alcohol behavior and if so, is this change in behavior linked to brain-behavior change?
Participants will be randomized to a treatment group (SUV or placebo) and protocol arm, electromyography (EMG) only or EMG+functional magnetic resonance imaging (fMRI). Participants will be asked to complete the following:
* Baseline lab visit(s) that include the psychophysiological stress paradigm (EMG only or EMG+fMRI, dependent upon randomization).
* Acute drug challenge where the participant will return to the lab to repeat the stress paradigm following administration of a single dose of either 10mg SUV or placebo.
* Medication trial where participants will be instructed to take 10mg capsules of SUV or placebo orally each night before bedtime for 4-weeks.
* Daily reports of medication adherence, side-effects, sleep, alcohol use, and mood will be collected via smartphones during the 4-week medication trial.
* Post-treatment lab visit(s) where participants will return to the lab at the end of the medication trial and complete the same stress paradigm from baseline (EMG only or EMG+fMRI, dependent upon randomization).
