I was addicted to caffeine for decades. A couple of cups a day. After dealing with digestive issues and my physician telling me I should quit, I decided to stop drinking coffee. Suddenly, my companion was gone. I was afraid that I wouldn’t be productive anymore. But a weird thing happened. My nervous system calmed down and after a few weeks, I actually felt more focused, relaxed, organized and effective. Life is better now. I’m 53 and never really struggle getting through 3 sets. Packing up my gear at 2am is a little rough but a couple of Advil helps get me home. Caffeine is bad folks.
