Timeline for Withdrawal. The predicted average timeline for Vicodin withdrawal symptoms to end, or significantly dissipate, is 7-10 days. That being said, in some cases, certain symptoms can last for weeks or months, especially psychological symptoms. I think however, that I should have waited a day or two after finishing the Hydrocodone before I asked my question of “is it possible to withdrawal from Hydrocodone after only a week.” After two days of not taking any Hydrocodone 7.-5/500, I feel pretty good. My back pain is gone. I need some support. I have been on vicodin 10mgs/325 3xs a day for 3 1/2 yrs for fibromyalgia. Past month I started having digestive problems and i was told gastritis, so i figured between taking these on an empty stomach (only way they worked) and taking advil daily its time to.come off all these pills. I took Vicodin after a Root Canal Surgery for the pain. I took at least 2 a night for a week in a half or so, and then I started to taper off by the 2nd week. Withdrawals After 2 weeks of using I was doing some bags maybe 3-4 a day or 60mg roxi for a week and half id say at the most, then I knew i was going to go through withdrawal so I took suboxone. I ended up taking about 17mg over 7 days, which end up giving me withdrawals from that, not so bad but I read if you do WD from suboxone and then do opiates again for a day or two you wont have WD from. Friends: I need some help here. I have been off of opiates (perks, oxy's, dilaudid) for 23 days. I have been taking them daily for 4 years and have been dopesick hundreds of times, and have never made it this far. note: after 3 weeks of opiate use your body will become used to the narcotic.

Vicodin withdrawal symptoms develop and change in the days to weeks following the last dose taken. People who are dependent on short-acting opioids like Vicodin may experience relatively early onset withdrawal symptoms that start within 6–12 hours of their last dose. Symptoms usually peak after 1–3 days and then resolve over a period of 5–7 days. 2 weeks is a normal course of pain meds. You should have VERY minimal withdraw if any. I never had any wd's after 2 weeks of use. Good luck :) You should have VERY minimal withdraw if any. I never had any wd's after 2 weeks of use. Vicodin withdrawal can produce a wide range of physical symptoms which can occur when someone stops or dramatically reduces the drug after heavy or prolonged use.
