I had that last year, went into total panic convinced I was about to die from liver failure, and then it was ok next time round. Try not to worry. If they thought it was something serious, I'm sure they would be looking into it further now, not looking at a retest in a few months.
Having said that, if you are drinking a lot, it would be worth looking at cutting down anyway as alcohol is famous for increasing menopausal problems, so you will probably feel better all round if you cut right back.
