Jonathon,
You can buy electronic copies of Andreas' books so that you don't have to wait. Buy it direct from http://www.1stbooks.com. Then search authors for moritz and you will see all four books. Once you pay, you can download the books to your computer soon thereafter.
A 2.7cm gallstone is big, but can easily come out with the liver cleanse, especially if its narrow dimension is less. I have removed half a dozen large stones, one even larger than hers. In the cleanses which removed the largest stones, I was using the liver cleanse taken from the book called, "Are You Stoned". It is different than that of ANdreas, and Hulda Clark. It uses twice as much oil and is taken over a 2 hour period. It is rigorous and has a tendency to make one sicker feeling due to more oil. You may want to get and read that book to broaden your horizons. I use Andreas' cleanse too, since it is a more balanced and safe cleanse for ongoing removal of stones from the LIVER, but for gallbladder I have had better results from the other cleanse. This does not mean that this is what you should do at this point. I have never used any cleanse to remove a stuck stone. The oil causes the gallbladder to contract and try to shoot out bile which it cannot do. If the stone is still in there in a few days of gentler methods you mihgt consider it, but it will not be pleasant. It would be a last ditch attempt to avoid losing the organ.
The problem is that the gallbladder is blocked and cannot fill up with bile from the liver, so another liver flush may not be helpful until after the stone passes. It would be favorable to get the stone out of the duct so you can do a liver cleanse, whether it goes back into the gallbladder or out into the main bile duct.
If she is stationary, she may want to try to exercise, bouncing on a small trampoline, and do some very deep breathing, exhaling all air from lungs then filling them all the way up. Be careful not to hyperventilate. This will massage the liver area and add some mechanical stimulation to moving the stone.
Make sure she keeps drinking tons of good quality water, with a sqeeze of fresh lemon juice in each glass. This will ensure that the mucus membrane inner surface of the duct can stay wet and lubricated. This combined with motion and the muscle relaxing effect of epsom salts will help to move it.
Getting sleep is imperative, since this is when the mind gets out of the way and body can take over its own healing operations. I passed my stuck stone when I relaxed and did deep breathing and drank a lot of water, I was in bed and trying to sleep. When I woke it was gone.
Consider that now that she is in this situation you want to get the best possible outcome. It is impossible for her to hurt herself short of surgery. It is really the pain that is the motivation to surgery now, and the fear of course. She should try anything and everything to avoid the surgery and within the guidelines of natural healing experts like Andreas.
Strongly massaging the area that is painful is the most direct way to stimulate it to move, even though it causes pain. Drinking lots of water will cause a lot of urination but that is what is necessary to wet the mucus membrane. Drinking epsom salts will relax muscles but it has a dehydrating effect on me, which is the last thing she needs now. Keep that lemon water flowing. Bouncing on a trampoline can help to massage the whole abdomen very effectively, as can just standing and twisting the body back and forth quickly. All of these things may hurt but they help to get the stuck loose and able to move.
It is unlikely that she understands the full impact of surgery on her life, because doctors are unlikely to tell her because they don't understand it themselves, or they would rather get the money for the surgery. After reading Andreas' book you will understand how important the gallbladder is to the body and you will be glad you saved it from the knife.
I think coffee enema would have little effect on moving the stone. It would stimulate the liver to produce a lot of bile, but that is not her problem. When she eats it should just be fresh soft fruit like orange, grapefruit, watery and soft and fresh. This will keep her strength up and keep the salt low. Most coffee is not good for enemas anyway, being to high in toxic chemicals and pesticides. There is one kind of coffee made for colonics, see the link at the bottom.
Sorry I don't have time to proofread, edit and organize my comments today, but I hope you can sort them out and find something of help for Monica. I'm sure people are praying for her, but your understanding of the problem and its natural solution allows you to pray for her in a more allowing way. Prayer will open the channels of learning and opportunity which can make this turn out OK for her. Pray expecting a perfect answer, and with peace and love in your heart if you want it to work. Pretend it is all finished and you are simply thanking your Source for the miracle that has saved her from surgery.
