He's talking about 800mg, and I doubt it. 400mg is well known to be a safe daily level. I doubt by doubling it you will experience massive negative side effects.

Here in Finland (possibly highest caffeine consumption per capita in the world?) there are people who have been drinking well over >1000mg/day for decades and life expectancy and heart health among the population is normal.
