quick question vike withdrawal

[nooo]

actually, two questions. i had a real problem with xanax and i ended it about 6 months ago, cold turkey. it was the hardest thing ever, and i started eating vikes outta habbit of swallowing pills i think. so ive been using them recreationaly for perhaps 6 months, and maybe everyday for like 2 months. i smoked some opium friday morning and i just felt like shit so i decided to stop it all, and today is tuesday, i was in the hospital puking blood, fingers tingling, i havent eatin in three days, i was wondering if thisis the withdrawal or just some virus i got. cause i didnt feel any pain, no pain at all like the way friends of mine addicted to more serious opiates have talked about, or the pain heroin addict friends of mine talked about. no pain at all, i was wondering if i was even addicted. the questions are 1how long does vicodin take to get addicted to? and 2 how long would the withdrawal be considering how short/long i took it?
