Help. Detoxed myself off hydrocodone after long time use. I wanted off. Last dose 8 days ago, W/D was not pleasant. In a ton of pain will 5mg restart w/d?

Ask your doctor. When you start to feel the detox symptoms from Hydrocodone will get very uncomfortable and this is what causes you to stay hooked on the drug. Ask your doctor for help, and detox with behavioral treatments which address the underlying psycho-emotional reasons and are very effective.
