I always loved DHC. DF-118's... But you definitely need a decent amount to catch a good buzz, so in order to suggest a dose we'd need to know about your tolerance. If you're opioid naive, try one, maybe two, then go from there. If experienced, you'll probably want to start with more than that.
DHC is a fairly mild opioid- 30mg is roughly equal to 10mg or morphine, and slightly less than 10mg of hydrocodone (according to my experience/conversion charts).
