This week as I tried to lower my coffee usage or stop altogether, I had dropped from 3 cups a day to 1. That one suddenly started to make me feel noticeably high, like a bump of cocaine in the morning. I realised that I craved it in the same way and it clicked for me - coffee is literally just a drug I like to take by myself and read the newspaper. It's no different. It's the first thing I think of in the morning because I'm addicted. Currently trying to go cold turkey.
