Query: easiest ever

this is the easiest most effective way to feel better and loose weight. a buddy of mine got me started on this and you can do it from 10 to 40 days..... i did it for 15, i lost 20 pounds, lost my heartburn trouble and got more energy for work. And NOT once did i feel like i was starving even thought that's all i had for 15 days. Everytime i was hungry i just drank more. And with work i am on call 24 hours a day and this was easy to keep up with and saved A LOT of money during the process (since this is all i had when i was on the go). Forget about pills and stuff.. i have tried them all...
