Jerry, I am so glad that you are going to AA. Just be patient, though. As you work the steps, you will probably feel worse before feeling better. You will be dealing with feelings that you have supressed with alcohol. Remember the great slogans: Easy Does It, It Works If You Work It, Let Go And Let God, etc. Those simple slogans can be life savers. Also memorize the Serenity Prayer and say it silently about a hundred times a day! LOL! Seriously...it's another tool that works.
I don't think milk thistle would hurt, but what you definitely need is a good one-a-day vitamin WITHOUT iron. I also take 500 mg of Vit. C and 400 IU of Vit. E daily. Drink a lot of water, preferably distilled. It will help flush out the toxins in your system. Avoid fried foods, fatty foods, and "fast foods." Eat lots of fruits and veggies and go easy on meat...it's the hardest thing for your liver to process. Beans are a great source of protein. Avoid processed sugar (donuts, pies, cakes, etc.), but do eat complex carbohydrates such as pasta, rice, peas, green lima beans, boiled or baked potatoes. Just basically "clean up your act" where food is concerned, if you don't already eat this way.
To suppress nausea, I find that Tums work well. Also, you can resolve nausea with a saltine cracker or two.
Ideally, NO meds is best for your liver. However, most of us do have to take some sort of meds. I don't think antidepressants would be harmful. I've had them prescribed to me in the past, by docs who were aware of my hepatitis. They can be very helpful to you at this time. Warning: Some AA members are staunchly antidrug in any form. I have seen people on bipolar meds flip out because they went off their meds. So it's best not to announce it to your AA group, if you do go on antidepressants. Those individuals are not doctors--at least not YOUR doctor. I hope you have a sponsor, and that person should know, but it's not necessary to make it public.
Hang in there!
