my mom had gallstones long time ago. she drank apple cider vinegar and some oil mixture as well as some pills. It did help, but she was literally sh1tting gallstones for 2 or 3 days.
I had also had the same prob just over 2 years ago. It was hell. The pain was very intense, doesn't matter in which position I was. (For me to say that you can believe it was intense...I had to ceasareans and never experienced pain. Hardly took pain killers as well, and couldn't wait to be up and about.)
I had to go for 2 ops: first was to enlarge the tube from the gall bladder to intestines so the gall stones could pass more freely. The second about 2 weeks later to have my gallbladder removed. After my op I was very sick and vomiting gall the rest of the day. Doctor was baffled by this, as it is not supposed to happen.
I do not drink coffee. Only had a taste of it a long, long LONG time ago and decided I do not like the taste (especially the aftertaste). But now I have to be very careful about what I eat. Even the slightest amount of fat (full cream milk, cream, ice-cream, chocolates, red meat, food fried in oil or butter etc) makes my liver hurt. So basically, I had to change my diet as well.
Can't remember what it cost, medical aid paid everything.
