I'm curious if you could reason this out for me. If I drink a few hundred litres of tea a day to keep me alert then why is that different to me taking ritalin? I mean its obviously impractical and probably quite bad for me and I should absolutely take ritalin instead. But I'd love to know why the desire the stay alert to the extent that I need to seek drugs to help with that because I can't get enough sleep is any less alarming if my drug of choice is tea (ie. Caffeine) rather than ritalin?
