Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this online research study is to determine whether or not a gradual caffeine reduction program developed at Johns Hopkins can help people reduce their caffeine use. The investigators will provide materials to help guide caffeine reduction and ask questions to track caffeine use over several weeks. The investigators will also assess how reducing caffeine may benefit common caffeine-related problems such as anxiety, sleep disturbances, and gastrointestinal distress. The study will also determine whether or not people like participating in this caffeine reduction program in an online format.
