Hey man you can do it. I am gonna embark on a 10 fast probably in about two weeks or so. The longest I have fasted yet is 3 days. For me it is a big mind game. Just keep in mind that can ultimately control your urges. If you feel the urges to eat just drink a huge cup o' water and go do some activity that you really enjoy and take your mind off of it. Read a book, play some music, do a puzzle, call an old friend, watch a movie, do whatever you gotta do. You can do it!
