To stop withdrawal symptoms of oxycodone or hydrocodone:
1. Take more opiates (i.e. Propoxyphene, Darvocet, Darvon
2. Take methadone.
3. Take large amounts of Tylenol and Pepto Bismol.
4. Also, I have used cough syrups and OTC sinus medications to ease the withdrawals, but make sure to take something to relieve diarrhea.
