I feel like I am always pigging out, is this really normal?

In the first week your breasts produce colostrum and experience engorgement; in the second week your breasts go into a transitional phase of producing kilojoule-rich milk, which has particularly high levels of fat and lactose (milk sugar). The mother’s super-hungry phase usually passes after those first couple of weeks, as your breasts settle down to produce mature milk. But things can remain erratic for another month or so, as your hypothalamus fully establishes the delicate balance between milk supply and demand. So, let your appetite go with the flow for the first few weeks. I always used the philosophy that ‘If I’m hungry, I’m not producing my best milk, and that’s not what’s best for our baby — so I should eat.’
