So I drink at least 8 shots of coffee every day of the week, and have done so since I started university in 2001. After I graduated I just kept on increasing, to the point where I could have 16-18 shots in a day and just feel "normal" (ie. no boost). I think that it is affecting my thought patterns and ability to "unwind", so it's time to quit. Not to mention the money that could be used for more productive purposes. What I need is some practical advice from those who have quit and stayed off the coffee. I have tried twice and have only lasted 1 and 2 days respectively. All help is genuinely appreciated.
