I can't speak to the acid reflux but my husband was diagnosed with fatty liver (technically he has NASH, which is non-alcoholic liver damage) several years ago. The only cure is major changes in your lifestyle to get you back in good health. This means overhauling your diet and exercising. So far he really hasn't done much about it, which is too bad because clearly his body is telling him it can't sustain the way he treats it.
If I were you, I would seek out someone in natural medicine who can help you with nutrition and perhaps some supplements to help you get back to good health. In my area, many chiropractors are well versed in nutrition and can design a program that treats your whole body.
