Thank you for posting your question here, I will try to answer it to the best of my ability.
You should quit drinking, other than that everything else you are doing is good for you. You can ask your doctor for some anti inflammatory drugs. Also reduce protein intake and instead increase carbohydrate
Do this for a week or two, after which get another blood test
done to check whether your AST levels have gone down.
And remember, high AST levels arent threatening on their own, so dont panic.
I hope this answered your question.
