So is alcoholism a mental disorder that stands alone, even without any consumption...or is the disease caused by the intake of alcohol?
It's my understanding that it stands alone- it's that first drink usually at an early age that starts things but not all who drink become alcoholic.
As for your other questions there could be lots of reasons why the person is still 'having problems' when not drinking- here are some ideas:
They have to make adjustments and learn new ways to live.
The problems are consequences are a result of their past drinking.
They can't cope with things without being numb.
They might just have problems that have nothing to do with not drinking.
They have damaged themselves from drinking.
Their maturation process has been stunted due to drinking.
Recovery is the process of dealing with all of the above. Being sober and living successfully.
I am interested to hear what other people will share.
