I know, for me, I can answer a solid 23/30 with a fairly resounding 'YES'.
My No's are 4, 8, 10, 14, 18, 24, and 27 (although that one is kinda the opposite ... NOT using has effected them more).
And trust me, 23/30 is MORE than enough to qualify on this little quiz
As Lily said, hydrocodone is considerably stronger, mg per mg, than codeine, both in terms of analgesia, and in terms of causing rapid dependency. It's a synthetic, turbo-charged codeine, is what it is. Not surprising that someone would prefer vicodin to codeine ... it's 'better', in every way ... until you try to quit taking it
