Elevated alkaline phosphatase

I recently had a liver function test as part of my regular blood work.  My alkaline phosphatase level was 145.0, where the normal range is 35.0-123.0.  My doctor told me that the results indicated that I have beginning stages of cirrosis (cirrhosis) of the liver, and I must not drink any alcohol, whatsoever.  I have 1-4 drinks/day  on a fairly regular schedule, but not every day.  Do these test results actually indicated cirrosis (cirrhosis), or is the doctor overreacting?  This is the first time I have been to this doctor, but he does seem to be an extremist on alcohol consumption.  What other tests do I need to have other than having another alkaline phosphatase test done in 3 months?
