I had quite a caffeine addiction but I recently kicked it. I was up to 900 mg/day at my peak. I think caffeine counts as an addiction. I had a strong dependency on it and couldn't function physically or mentally without it.
Too much and I get strung out and too wired to work efficiently. And.... it makes me tired not long afterwords. A little tiny bit in one or two doses a day isn't bad but much more and it becomes counterproductive.
My favorite drugs? A good light meal, fresh air and a nice long walk in the sunshine.
If it affects you in a negative way and you cant stop, that is addiction.
How many cups would that equate to?
