Not really sure what to say here... most peoples caffeine anxiety comes from overdose, well, not even necessarily that but generally high amounts. I'm usually fine with caffeine, but I just had a cup of normal tea... (British, with milk and sugar). I wasn't feeling particularly anxious at all prior to dose, but was suddenly overwhelmed with oversensitivity, extreme restlessness, pacing around the house wired as hell for a solid 30 minutes... why? I also felt extremely tired and fatigued throughout all of this but proceeded to do it anyway, now i'm exhausted and extremely aware. Coffee, and large doses have not caused this in the past with me at all, even when already very anxious. Any ideas on why on earth this happened? It was extremely forced, more speedy and uncomfortable than an Amphetamine high, but the dose couldn't have been higher than 30mg. I know i'm not sensitive to caffeine as higher doses haven't caused these symptoms... calming down now... anybodies input is highly appreciated.
