I have been taking neurontin (1800 mg currently) for 3 years. I was Rxed vicodan about 6 weeks ago. I also take tramadol for pain. The vicodan is more effective than anything else - hands down. I try to get by on just the others but often white knuckle it until i have to take the vocidan. And then I get a few hours of complete relief. My Rx for vic is 5 mg tabs - 1-2 tabs 4xs a day as needed.
