Throughout my diet, there have been many times I wanted to give up and even times, I did give up. After a week of ben&jerry's, I got back on the horse again. The key is finding a diet that works for you. When I started, I wasn't aware of all the diets out there.
Sure I knew of the big ones, Atkins, South Beach, etc. But there are so many others and one of them may be the diet that actually works for you!
Check out the site I used and so far so good!
