hi i was reading recently on: HOW DRUGS AFFECT NEUROTRANSMITTERS. that "Chronic consumption of opiates inhibits the production of cAMP, but this inhibition is offset in the long run by other cAMP production mechanisms. When no opiates are available, this increased cAMP production capacity comes to the fore and results in neural hyperactivity and the sensation of craving the drug." so if i take a vitamin d supplement (assuming thats the supplement that would fix the production of cAMP to reduce cravings?) would that help returning my brain neurochemistry back to normal? anyone have any insight into this or supplements that are neuroprotective if you are a chronic opiate user (oxycodone, about 80mg a day in my case) such as myself.. thanks bl! :D
