I just shot an espresso and it is the first time i have felt caffine really give me a boost - i can feel it buzzing about my head. quite the fun time. i stopped getting the nicotine high a few years ago beofre i stopped smoling semi-regular... but can get it again which worries me as i might take up smoking again because of that... grr

i don't get a alcohol buzz anymore apart from getting blind drunk. :)
