For the liver i take a vitamin or supplment called Milk thistle it helps the liver clear its self of toxins... It might be worth taking i take it everyday 4 times day.. I dont want to hurt my liver and be on a list for a new one of those... Its scary.. i have also been told that liquid meds are easier on the liver... Its just a reccomindation... Maybe those things will help in my opinon 6 vicodin is not over doing it as long as you and your doctor are ok with it.. i have heard of ppl that take more... its just all on a personal basis..
