The study will investigate the efficacy of Sleep Healthy Using the Internet (SHUTi), an online insomnia intervention, in reducing alcohol consumption and improving sleep in heavy drinkers with insomnia. The participants are ages 18-50 (N=100) who have insomnia and are heavy drinkers (at least weekly binge drinking episodes \[4/5+ drinks in one sitting for men/women\]). This intervention has a mixed methods randomized controlled trial design. Participants will be randomly assigned to either the online SHUTi intervention (N=50), or a patient education (PE) website (N=50). Quantitative data will be collected via online REDCap surveys and daily online diaries. Qualitative data will be collected via semi-structured telephone interviews. Data collection points will be pre-intervention, post-intervention, and 3- and 6-months postintervention.
