If you do want to taper, I'd search it but I was taking more than you and went cold turkey. I began to taper and felt so bad I just went for it. Why drag it on... But everyone is different...
Congrats on 6 months in aa.... You should know a ton about this stuff if your really working your program and just because you have a script doesn't mean your not addicted or abusing, you've become dependent. Opiates like vicodin are crazy on your system. I'd recommend looking at the thomas recipe and amino acid protocol which I really like. EVeryone is different so find what works for you but quit now! Every pill you take makes the withdrawals so much harder especially when you under 6 a day... You can go cold turkey, it'll hurt but you'll be clear headed before you know it and then you'll see how even those amounts can cloud your life. Good luck!
