Joe, those looked very fresh. They almost did not stink were very homogenious inside and out, and very light. All previous smelled disgusting, looked awful and seemed a little bit heavier.
I recently came back from 1 month holyday on a sea side where I was quite often eating in restaurants. I felt pretty sick several time after the food. Since I started to eat only food that I cook using only natural fresh products, I became quite sensitive to any bad foods.
Also I am 7 month pregnant and female body tends to dump bad things, that baby don't need, to the liver.
I keep clensing every two months and I believe those stones develop during these breakes.
