I know exactly what you are going through. I went through it when I was 20 and my sister just had her's removed 2 weeks ago after suffering horribly with it.
I have something that will help you to get rid of some of those stones while you are waiting for your surgery which will help you tremendously with the pain. The pain is caused by the stones moving through the duct work in your system.
I will tell you this the colder you keep this drink the better it will taste but it doesn't taste the greatest. But it does work and it's all natural. You should really do this twice 2 weeks apart but you don't have time to do the second round but this will help remove the ones at the front so you'll have some relief.
Ingredients: 4 Tblspoons Espom Salts
1/2 cup of Light Olive Oil
2/3- 3/4 cup Fresh (not canned) grapefruit juice. Meaning buy the whole fruit and squeeze the juice out of it.
1 Pint sized jar
Ornithine (found at the health food store) take 4-8 to help you sleep through the night.
Choose a day like Saturday, when you will have the next day to rest. Take NO medicines, vitamins or pills that you can do without, they could prevent success. Eat NO FAT breakfast and lunch. (Try cooked cereal with fruit, fruit juice, bread and jelly but no butter. No milk. Baked potatoe with steamed veggies with salt only no butter. This allows the bile to build up and develop pressure in the liver. Higher pressure pushes out more stones.
2:00pm on Saturday
DO NOT EAT OR DRINK AFTER 2:00pm, if you break this rule, you could feel quite ill later. Get your Epsom Salts ready by mixing them with 3 cups of water in jar is easiest. This will make 4 3/4 cup servings. Set the jar in the frig. to get it really cold. Remember the taste thing.
6:00pm on Saturday
Drink 1 serving size (3/4 cup) of the salt water mix. It's ok to drink a couple of mouthfuls of plain water after to rinse the taste out of your mouth. Get out your olive oil and grapefruit juice.
8:00pm on Saturday
Drink 1 serving size of the salt water mix. It's important to not be late on this time frame by more than 10 minutes.
Get your bedtime chores done now.
9:45pm on Saturday
Pour 1/2 cup olive oil into the pint sized jar. Squeeze the grapefruit juice into a measuring cup and remove pulp with a fork. You need to have at least 1/2 cup of juice or more up to 3/4 cup. Add this to the olive oil, close jar and shake shake shake it up. Then go to the bathroom and be ready to drink your mixture by 10:00pm.
10:00pm on Saturday
Drink the grapefruit/olive oil mixture. And take 4 of the ornithine tablets or more if you already suffer from insomnia but not more than 8. Note* Drinking this through a large straw helps it go down easier. You may use ketchup, cinnamon or brown sugar to chase it down between sips. Make sure you are standing up when you drink this all. Drink the entire amount in 5 minutes. Then Lie down immediately. The sooner you lie down the more stones you'll get out. You'll actually feel them moving through your system but it won't hurt because the bile ducts are open now thanks to the epsom salt. Now relax and go to sleep and let your body do all the work.
When you wake up take your 3rd does of the Espom salt mix if you notice you have indigestion or nausea wait until it is gone before drinking the salt mix. Now go back to bed and lie down. Important not to drink the salt mix before 6:00am Sunday.
2 hours later drink last dose of salt mix and lay back down.
After 2 more hours you may eat now, however start with fruit juice, 1/2 hour later eat some solid fruit. 1 hour later you may eat regular food, but keep it light. By dinner time you'll feel recovered.
Finally, expect diarrhea in the morning. The gallstones will float and should be pea green, as only bile from the liver is pea green. You may also notice Chaff floating on top of the water as well. Sometimes the bile ducts are full of cholesterol crystals that did not form into round stones. It should be tan in color. The harbor millions of tiny white crystals that are cholesterol. Cleansing the Chaff is just as important as purging stones.
This is really simple to do, taste blah but does work to help relieve some of your pain.
Good luck with your surgery and hope you get to have the laproscopic one instead of the traditional one I had to have 20 years ago. God speed on your recovery.
