You might have to bite the bullet and try some flushes. Just use any oil that is tasteless and start off with less than 1/2 cup to get use to it. Do use grapefruit juice with it. Put it in a jar and shake hard to mix it, it becomes watery. Drink it over the sink, in case you can't hold it, and always keep your nose closed even when you take a breath in between. Rinse your mouth with water or juice and spit it out in the sink and then let your nose go and suck on an altoid or something like that. You can also add some ginger to the drink.
I used to get nauseous thinking about the flush, but I kept improving my system and now it is easy. I hated olive oil. But now I have found there are different kinds, I went from Italian to Spanish and now Greek, the mildest kind made from Kalamata olives.
I have also tried safflower oil.
It is up to you do you want to suffer or get better.
BTW I did my 1st flush when I was 67 so it can always be done. My mother had gallbladder trouble too and she lived with and never had the surgery.
Sorry I just noticed this is the surgery forum and you were looking for people that had surgery. Most people disappear afterwards so you might have to read all the messages and look for answers.
