My caffeine addiction

I'm not alone.

What I learned (well, I knew it but now I can prove it) from this article:

1. Caffeine "slips effortlessly across the blood-brain barrier" and blocks "the adenosine telling us to go to sleep because we’re tired". However, small amounts throughout the day don't seem to impare sleep.
2. Caffeine produces a high similar to cocaine, and like cocaine "the brain develops a tolerance to all of these drugs, ever-increasing quantities are required to achieve the same high." The good news is that caffeine has a "built-in restraining mechanism. Technically called caffeinism, it’s the state in which an overcaffeinated user hits the drug’s “dysphoric” range and is overcome by the shakes, anxiety, tension, and nausea... Too much cocaine makes you feel invincible; too much coffee makes you think you’re having a nervous breakdown." Oh, and I have been there! (With caffeine; no idea about the other.)
3. Drinking coffee before breakfast is bad. "A study released in late May found that drinking coffee before breakfast could cause blood-glucose levels to rise sharply, which can be dangerous for people with type 2 diabetes. " Plus it gives me a stomach ache and my muscles get tense.
