Now days I have very hard cravings of food that's high in salt and sugar, like I want to eat something salty and crispy, I am having these cravings from a month and dur to this my weight is getting out of control. Can you help me with information on it. I work from 5 pm to 3 am, I eat my first meal or anything eatable of the day around 3-4 pm, then the most hard irresistible craving kick in after 3 am when I reach home. I try to fight it but I can't, I have medicines, I have diet plans, I have lot of things but the most I want to know is why. I know this eating is something abnormal for me and this is have something to do with my degrading health and weight gain.
