Help--I Need To Lose Weight Fast!

I know I have said this before on this blog, but this time I must act. I can no longer tolerate my image in the mirror. Really! I wish I could get some fast weight loss tips. I tried a four-day diet about a month ago, and it seemed to work, at least a little, but I put the weight back on when I went on vacation the following week. I am going to the grocery this weekend and buy the items so I can do the four-day diet again next week. Wish me luck!
