Now I dont know about Hydrocodone, Oxycodone is what your gonna want if you can get em. The feeling is fucking amazing, and the effects last for at least 4 hours of pure euphoria and bliss. And for me at least Ive only gotton a bad come down once and that was the first time I did it and since then no come down, it just drifts away leaving you with a nice glow. MAN I LOVE EM, MAYBE A LITTLE TOO MUCH.
