If you don't feel you can do this alone, ask a friend or family member to hold you accountable to reducing or stopping your news viewing. Having someone to help you adhere to your goals will provide you with a greater chance for success, especially if your obsession has been bugging them or interfering with your relationship.  Alert your friends and family to the telltale signs you’ve been watching too much cable news, such as becoming easily agitated, paranoid, not answering the phone, panicked and restless.  Make a point to check in with your family and friends. Don’t wait for them to ask you how you are doing. Consider saying something like, “Hey, I wanted to check in with you to let you know how I’m doing with changing my news viewing habit.” This will provide a lead in for them to feel comfortable to ask questions. Set a maximum amount of time that won’t interfere with other activities. Typically 30 minutes of news can provide you with ample coverage; any more than that and it gets repetitive.  Create a schedule of all your daily events. Include news reading, viewing or listening as a small portion of each day, and no more. Setting limitations and tracking your time on a daily schedule or planner will help you hold yourself accountable to your goal. Apply the same rules to internet news. Give yourself a chance to break your news addiction by limiting your online news reading to set times of the day. If you see headlines, don't click to go there unless it's during your allotted time. If you watch more than your allotted amount of news put money into the jar. The money will be given to your friend or family member. Or, it could be donated to a non-profit organization that helps people with addiction. This principle is similar to using a Cuss Jar when trying to stop a family member or yourself from cussing. Instead of cussing, the goal can be news watching. Pick an amount of money to insert into the jar for each violation. You can also get someone to agree to add money to the jar when you go an entire day...
