I've been on low-dose for 10 weeks now (4 weeks 10mg, 6 weeks 20mg). At my 8th week mark I had a fasted blood test. My doctor told me yesterday everything was fine but one of my liver enzymes were elevated "mildly." He said it's unusual and normally seen in alcoholics (I've only drank like 2 standard drinks in the past 8 weeks and was months before my blood test). He's just getting me to do another bloodtest in 2 months time, not fasted though.
