Thanks for all the comments and advice. Thinking about my increasing caffeine consumption over the past 10-20 years. Noticed a trend towards more and more caffeine in the marketplace, in various forms, and a lot of marketing to go with it. 30-40 years ago McDonalds was Big Mac, Fries, and Shake. For the past 20 years it has become more about the Big Coke, and now they are pushing the coffee, which is really good by the way. Can't fault them for keeping up with the trend. The marketing of energy drinks to kids by Red Bull etc does concern me. Gotta keep a closer eye on caffeine consumption. These headaches and aches and pains piss me off. I know a big coffee would fix me right up, and that pisses me off even more. Gonna try cold turkey for a few days. When I do go back, it will be a smaller coffee, good quality, and just one in the morning. Cheers.
