It really won't be that bad, Really. Go for it, you can do it. I've come off much more hydrocodone than that and took it longer too. And worked while doing it. I read water meters and walk 10-12 miles a day. It's hard work, most people (4 out of 5) don't even make it a week at my job. And I did it, and did not even miss one day of work. Hydrocodone withdrawals are mild, really. Just eat a lot (force yourself) and drink a lot of fluids and take as many warm baths (baths help a LOT) as you can. If you can, take a few Valium or Ambien here and there for withdrawals, but only for 5-7 days. That way you don't get addicted to those. But sleeping through as much of the withdrawals as you can is never a bad idea. Just don't touch that Valium or Ambien after 1 week any more. Probably won't even need it a week. Maybe first 5 days and that's it. Get free and clean again!
the first 3-4 days will probably be the most intense. they will be flu like symptoms. good luck to you :)!
