I heard that story on Nyc radio. I drink a lot of coffee each day, and even so I feel better with it then without. When I get droggy, it is as though I am walking around half asleep in a dream state, so everything feels worse. I have health issues, and it also tires me out, so I feel like if I didn't drink coffee, I would be sleeping on the couch or in bed too much, which was the case a few years ago, when I wasn't being treated. All in all, my mental health has improved even with the coffee. Better to live outside of sleep then asleep.
