thanks a lot for the information.
Unfortunately, "sleepiness" is a side effect with all opiate-based analgesics. Hydrocodone generally makes one less sleepy than the others. However, most people get used to the extra feeling of fatigue within a few months.
Oxycodone is an opiate analgesic which some people feel is a stronger than hydrocodone, and comes in a long-acting/ extended release formulation called Oxycontin. Maybe ask your doc about Oxycontin?
