question: HI  I have been done for drink driving,  I am an alcoholic but have taken milk thistle for fifteen years, but have to have a medical before i can get my licence back. I have to have a urine and blood sample. I have done numerous urine test strips at home for bilibrubin and eurogloblin and they are negative. But the blood test involves ALT AST and GGT I am worried that they will be high. I cant tell my GP, and i cant do the blood test myself.  How can I   a.. find out if they are high or   b ..reduce them if they are.  Thanks Ellen
