So easy to put weight on in this days

Hi, everybody. I had chinese takeaway on thursday last week. I was on night shift and I was very tired. I was thinking, that will be ok, but it wasn't. And I was out on friday night. Since I put 4 inchis and lost 5 inchis. My weight today is 10 stone 3 inchis. So I am not eating takeaway any more.
