The purpose of this study is to determine whether a gradual caffeine reduction program developed at Johns Hopkins can help people reduce their caffeine use. The study will also determine whether people like participating in this caffeine reduction program in an online format.

Study participation will include:

• A screening video visit to determine whether you are eligible for the study, which involves answering questions about your medical history and caffeine use.
• Eligible participants will then complete three more online video visits and complete six online surveys sent via email.
• The total possible amount of money you can earn for completing this study is $160.
• You will be enrolled for about 14 weeks.
