My DOC (drug of choice) was not the same as yours. But I have been learning and reading a lot about helping to restore my brain/body after the damage drug use has caused. Here's a link from the health pages that may help.

Also, I've been reading a lot about trying to regulate and heal natural dopamine production in my brain which the above article refers to. The info I have learned about the amino acid L-tyrosine.....at least the main sentence "Tyrosine is important to overall metabolism. It is a precursor of adrenaline and the neurotransmitters norepinephrine and dopamine, which regulate mood and stimulate metabolism and the nervous system."
You, of course, could read much more about it. There are a lot of articles within MedHelp's site about this amino acid. You can't take it if you are on an MAO inhibitor, but it helps with lots of things that drug addicts are still lacking or not producing on their own. That link up above talks about some fairly long term effects on the brain. It may help.
Most importantly, of course, is WAHOO FOR YOUR 10 YEARS!!! What have you done to remain clean? Love to have you share more if you care to. We all need to learn from each other. Thanks for posting~
