Always eating chocolate

I ate a lot of chocolate cookies again today. I tried to avoid them but what ever I do I can not avoid eating them. They are always there tempting me every time I open our pantry and every time I am in the grocery I keep telling myself not to get any cookie but still I am weak and end up with them in the sopping cart again. I wish I could stop eating cookies because they are making me big. No matter how many diet pills I would take I can not loss weight if I do not stop eating cookie. We all know that it is not good to eat cookies all the time because they are sweet and bad for our health but I do not know how to stop eating them.
