I am a binge eater?

So I have been on a diet for about a month now, and I find myself binging on good foods the moments they come into vision and I am alone with them. At work we have free er tarts and muffins and I find myself eating 4 or 5 within the hour, and then I just keep telling myself tomorrow I will get back on my diet. But I want to stop this madness! How do I recover from these horrendous binges I have been having?
