There is nothing wrong with getting in opiates, great high, nice buzz, as long as you are deciding to take them because you want to. Personally hydrocodone greats a amazing euphoric, as does OxyContin, or Methadone, or any Narcotic Controlled Substance. First time when I tried Vicodin 5/500, I took about 5 which I thought was a great experience, more social in Work, School, and Home with friends. There was not to much bad effects afterwards, wasn't nauseous, nor depressed afterwards, nothing bad came to my intention. So I would recommend for a good low tolerance high anywhere between 25mg - 35mg, so I would pop 4. If you ever decide or you want to take more the day afterwards ( wouldn't recommend, I would take It every week, choose a day of the week) then go with around 40mg - 55mg, be aware of the Tylenol your taking in as it is bad for your liver.
