Greetings! I have fibromyalgia and chronic migraines and I've been taking a low dose of Vicodin for several years (on and off). I'm prescribed 10/325mg hydrocodone/acetaminophen three times daily, as needed. The 10mg dose is the most I'll ever take in a day, and that's spread out over several hours. If I take any more than 5mg, I get nauseous. Anyway, long story short, I have needed to take at least 5mg almost every day for about two months now. I didn't take any yesterday (after taking at least 5mg every day for two weeks) and I started getting flu-like symptoms, which I understand are common withdrawal symptoms. But here's the thing: I never need to take more than 5 or 10mg to get the same amount of pain relief. I'm happy to get any kind of feedback about this. I'm not sure if I should be concerned about the Vicodin use. I never, ever take it recreationally. I only use it for pain and I've never had to increase my dose
