Bi polar effect on dopamine question..

[MadHatterMike]

Does anyone know how much oxcarbazapine effects dopamine or if it blocks a bunch of it..been reading up on its effects wondering if I'm having a problem feeling opiates at all because of long term use of bi polar meds and SSRI Zoloft daily for about 11-12 years. I did take bupe around 10 years or more but been off for 2months and a week now..however nothing opiate related is felt at all.
