Can stoping alcohol all of sudden is dangerous?and also liver fat can be get cured..?

Depends on amount: Delirium tremens (dt) is an acute episode of delirium that is usually caused by withdrawal from alcohol and it occurs only in patients with a history of alcoholism. But with fatty liver, either as a complication of excessive alcohol use, or in combination with non-alcoholic fatty liver disease (nafld), the build up of extra fat in liver cells can cause liver damage. See a liver doctor for help.
