Thanks, I'll check that out. unfortunately, my liver was damaged from an anti-fungal medicine more than 20 years ago, and I now seem to be very sensitive to things. I actually used to blindly trust doctors, and am now paying the price. (one of potentia side effects of the anti-fungal medicine was liver damage, and a test was supposed to be done after the first of three doses (one per month), after the second dose, I got hepatitis from it. When I asked the doctor why she didn't do the test, she thought that it was such a rare side effect that it didn't warrant doing the test! If I knew then what I know now, I wouldn't have even begun the treatment, and I would have made sure that test was done if I had.
