I actually have no idea who CGP Grey is. But I’ve just discovered his fun, funny, and provocative videos, which explain everything from why the penny costs us money to why we love our natural-pesticide beverage (coffee). Great stuff! You can see the lineup on his blog page. But here are a few to get you started:
Death to the Penny
Coffee: Greatest Addiction Ever
There’s lots more. I especially liked:

Caffeine may have some physical health benefits, but we need to be more aware that it causes/exacerbates anxiety and other mental health conditions.
Just read the 170+ pages of comments of people trying to get off caffeine here; http://coffeefaq.com/site/node/11
And the research referenced here; http://caffeineevaluation.blogspot.co.uk/
Many people feel they cannot 'get going' in the morning without caffeine; in reality they are just experiencing withdrawal from not having ingested any over the previous hours.
A key point is the research showing anxiety sufferers can be very sensitive to caffeine; some people think 'it can't be the caffeine, I only have 1 cup a day', but for them that could be the key issue in their anxiety.
Withdrawal is not easy (especially first 2 weeks, when anxiety actually goes up), but is possible.
How about cutting all caffeine for 30 days and seeing how you feel?
