So I had to do this for post surgery. It works. Hehehehe ( evil dr. laugh) Step 1- Do not eat for twenty four hours. Just liquids. Most of you will feel grouchy near the end. Tell loved ones and family to either get use to it or leave....it is only going to get worse. 2. Buy a 64 oz gatorade. Flavor that you hate. Pour out one quarter. Now combine that with a bottle of miralax. I think it is about 258 mg. It is 14 servings of the stuff. Guzzle it down over the next hour. You may need to thin it out with some water it gets kind of thick. 3. Time is now of the essence. Stock a bathroom with magazines a laptop and several rolls of cushiony toliet paper.Tell all other residence of the dwellling to stay far away. 4. Over the next 12 - 24 hrs you will lose a lot of weight. At times you will feel like you lost internal organs as well, at other times you will just wish to die. Whatever happens....do not I repeat do not give in to the temltation to strip naked and lay under the shower and let whatever happens happen. That does not end well. 5. When the waterworks subside do not eat a lot. Nibble. And weigh yourself. Enjoy the weight loss. Sure, it will return with in a few days of proper hydration, but u til does you still weigh 15 pounds less. Disclaimer....this is joke .Do not do this. IT SUCKS. I HAVE to do it occassionally and it is enough to make me consider if cancer really was all that bad.
