well, you wouldnt feel high because you are using the drug for what it is actually made for; ANXIETY! I was a recruiter and have interviewed hundreds and hundreds of people over the years. however, I worked in the IT field so it was a more mature/intelligent type crowed but people still were VERY NERVOUS at times when questions were asked or if they did not fully understand the question/job itself. you'd be surprised the looks/sweats/shakes you get w/ these interviews.
an anxiety med is made for things like this; NOT A XANAX, tho. then again, I seem to think all benzos are very similar but you'd want one w/ a longer last effect. not sure what job this is for or even what TYPE of job but an interview may last more than 15 minutes and the xanax will surly help but you wanna be chilled out, so maybe go w/ a konlopin thats if you even have the choice; if not, get ANYTHING you can. I see you already had the interview and said it went well. IF a round 2 comes about, that means you are one of theirs favs, so make sure all goes well and take another anxiety pill to make sure you are the same person as before; the one they liked, ya know!?
what type of job if you dont mind me asking? how old are you? any news yet from the company/people?
