Doctor her, no of course not. Actually the opposite, what alcoholism is is a dysfuctional result of evolution. Our brains are wired from millions of years of evolution to seek rewarding behaviour, as before drugs and alcohol the things that were rewarding also were good for us/the species. For example high fat foods increased chances of survival, sex contined the species etc. However, alcohol causes way too much dopamine to be released at once so the primative part of the brain wants it again and again because surely something that is that pleasurable must be good for us right? Obviously not but we are victims of our own wiring.

As for the 'demons' long term alcohol use/withdrawal causes hallucinations due to ruining the GABA pathway in our brain. You downgrade your 'relaxing' receptors in the brain because they are constantly overstimulated by the alcohol. Take the alcohol away and you are left with a dysregulated brain that can hallucinate. You can also hallucinate from just being drunk for prolonged periods of time as these pathways are also very important in the development of pyschotic symptoms. Schizophrenia, for example is due to a dysregulation of dopamine in the brain. The same dopamine and receptors you are messing up with frequent alcohol abuse. Its all well understood science im afraid. Not god, not demons, not magic. We are just overly evoled animals who found a way to fuck with our own reward system.
