Your not the only one........
I perfer a good dose of Hydrocodone over Oxycodone any day of the week.
The reason being is because I find Oxy to be more of a speedy less sedating/nodding type of Opiate, and though I've never had the pleasure of trying smack, I like that "I cant move and drooling on myself nod" than a psuedo-speedy opiate buzz with no real heavy "nod"(oxy).
Not sure what kind of oxy you've tried, but the ones I get (OC/80) imprints and they are greenish color cause me to nod just as much as any dope I've done (I only bumped the H). I've had other oxys, generics, I believe and nothing really happens when I bump it so I have to eat them. The high isn't nearly as good tho.
