"i take oxycontin 60mg 3x a day, and roxycodone 15mg 4x a day for chronic back/neck pain. sometimes i do too much walking, or get severe neck pain that the pain meds don&#039;t control. i add one 25mg vistaril and it enhances my pain meds effectiveness. about 3 to 4 hours later i become extremely drowsy, and often fall asleep, not good in the middle of afternoon! i think the occasional ativan is almost as helpful, w/o all the sedation. good drug, only if i can afford to be asleep."
