First you are doing a lot of really good things to help your liver. Getting off those drugs is huge good thing - IMHO.
You could add the juice of a lemon daily... in a glass of water first or last thing, in lemonade with a good raw honey, or maple syrup or agave and maybe a sprinkle of cayenne would be an extra boost. I find it helps me and I have a family history of liver/gall bladder problems.
