Wernicke-Korsakoff Syndrome/Psychosis and Alcohol Related Dementia are pretty extreme phenomena and the result of chronic malnourishment over a long time. You mentioned that you eat, so I wouldn't really be concerned about it..
Update: tests showed everything normal no pancreatitis, livers fine, gallbladders fine. I still have symptoms whether I abuse drugs or not so obviously I have gone back to abusing drugs. They told me further advanced tests will be needed, that might take months to schedule. The most likely guess I got was that I've ruined my stomach.
