autoimmune hepatitis

I actually have a few questions, so i'll simply list them, i hope that is ok.

I got diagnosed with aih 7 months ago, after the birth of my daughter. I was started on 40mg of predniselone and i am now down to 10 mg, i am also taking azathioprine. So far all the blood test results have been getting better and will shortly be going down to 8mg of the steroids.

What are the chances of my aih reoccurring when i come off the drugs in a couple of years? Is there anything i can do to avoid it reoccurring? i.e. Any peticular diet or milk thistle.

Can i drink alcohol and how much?

Could being on steroids for a long time cause liver failure?

What are the long term side effect of azathioprine?

And lastly, what is the life expentancy of someone with aih?
