What Do My Lab Test Reports Indicate?

Question : I am 46 years old, 235 lbs, 5'10" tall. I was a medium drinker for about 8 years until 2010 and then increase to a heavier drinker from 4 to 6 drinks during the week and more on the weekends for about 6 years. Last year I decrease my drinking up until Sept 2016 and then increased again. For the past two weeks I have been moderate at drinking and am mentally ready to continue this. for 15 months I have been eating well with salads 4-5 days a week, vegetables and supplements. Also, had a normal result from my endoscopy last year. My question is the following - March of 2016 my liver panel and blood tests were all normal in addition to a normal physical. This included AST, ALT proteins, white count, bilirubin, etc. If I continue with a moderate drinking lifestyle going forward drinking only on weekends no more than 4-7 drinks in a day, in addition to the other lifestyle changes, will my liver results this spring continue to improve or at least be the same as last year. I have a momentary set of nerves after reading about liver disease too much. Also, no live disease in my family.

I understand. My primary question is this" would the alcohol consumption over the past 11 months be enough to severely damage my liver, after having a very normal liver panel and blood work last year." Would the past 11 months be enough to drastically change my liver health from the apparent healthy liver of 11 months ago.
