Jeree,
I understand your frustration. I had a similar problem in 2010/2011 when I had my recurrence and entered a clinical trial of Carboplatin/Gemzar/Iniparib. After my first treatment, chemo was delayed almost a month because my liver enzymes were too high. They'd go up 10X the normal level. I tried everything, but found that Milk Thistle worked the best for me to help get the levels back down enough where I could continue with the clinical trial. I shared what I was doing with my onc and she was ok with me taking the supplement. Always discuss with your onc any supplements you might take to make sure they agree. When I get blood work now, my liver enzymes are back to normal levels.
Here's a link to a thread I created on the subject.
