According to Wikipedia half life of Caffeine is 2.5 – 5 hrs, not 5 – 6 hrs. Especially TED videos should put extra emphasis on having their facts straight.

I don’t drink coffee and alcohol. I don’t eat candy, chips, cake or anything with excess amounts of sugar and/or fat. I also don’t smoke or do drugs. Neither do I work out.
I just get up early in the morning to learn Russian, then go to school and after that, watch YouTube.
That probably sounds boring, but my future looks good, and my present is also pretty good.

Kind of a coincidence that I saw this. I quit caffeine about three weeks ago after a cup of Starbucks Nitro basically induced a panic attack. The first week without caffeine was ROUGH but once I made it over the hill I noticed I sleep way better, wake up feeling refreshed, no more “micro” headaches in the afternoon, and my energy levels are far more steady.

If you say that a quarter of the caffeine you had earlier makes it harder for you to sleep, what say you to the people who drink caffeine and go right to sleep? It’s completely contradictory. It can’t make it hard and at the same time not affect you.
