The only thing that would mildly concern me is the urea level (BUN). I am no doctor, but I am a radiologic technologist, and if your BUN continues to rise (or if your creatinine rises) you will want to be aware of it in the event that you need a CT with contrast. Contrast is hard on the kidneys, and the only patients that are routinely tested pre-scan are those over a predetermined age (some places 50, some 60) or diabetic. Nothing to worry over, just something to be aware of.
As to alcohol, your liver numbers don't look bad, and if your serum bilirubin and alkaline phosphotase are good, you should ask your doctor if you can drink moderately. I guess the question would be, what prompted you to give up alcohol in the first place?
Is your recommendation based on the LFT/KFT numbers?
My only recommendation is stay off alcohol completely as if there is or is not a problem now with the liver, it will most indefinately cause one. I am not prosuming to tell you what to do I am only talking from experience. If giving up alcohol is a struggle for you then as I am sure you know, AA is always welcoming for anyone.
I hope all is well
