i thought this had already been proved quite some time ago but there’s evidently more research showing that a cup of tea is good for your health. caffeine relieves headaches just as well as ibuprofen and better than a placebo. my only concern with using caffeine as a pain killer is that i wonder how many of the “tension headaches” that were relieved by caffeine were just caffeine withdrawal headaches? i presume the researchers took that into consideration but the article doesn’t say.
