Hey Doc, I Recently Went For A Blood Test And

Hey doc, I recently went for a blood test and had elevated alt levels (at 95). First part of the question is how high that number is, and if a night of drinking before hand could affect my levels I had a 6 pack the night before). I'll be tested again in 3 weeks, but I haven't touched alcohol in two as of last night, as I need my levels down for my doctor to be okay with prescribing vyvanse. Would a couple beers tonight throw my last two weeks out the window?
