As someone that quit caffeine over quarantine, I cannot even imagine slurping half a gram of pure caffeine. I probably wouldn't sleep for a few days and I'm certain my teeth would chatter my filings out. I know it's an experiment and the people were consented, but man, that seems a bit ... mean. There's no way I can see having that much caffeine nowadays and not be a total wreck.
