Yes, it is perfectly normal to get hungrier for a while when you first up your calories. Most of us experienced that. It wears off though once your body gets more used to having a decent amount of quality food available to it.

Regarding cheat days, I guess this is up to you. Most of us find that we no longer 'need' cheat days because the increased calorie allowance leaves a bit more room for the occasional treat, making us less likely to crave certain foods as they can be fitted into the diet as and when and no foods are off limits. This is designed as a lifestyle, i.e. something that you will be able to do forever. Obviously that means making room for treats, holidays, etc. as life throws them at us.

Some followers go without logging at the weekends to allow themselves a bit more freedom, others log everything every day. You have to find what works for you. If a cheat day makes the mental process easier for you then so be it.

It really depends on how many calories you are eating in total. So if your 1500 plus your cheat meal will put you over your maintenance calories for the whole week then NO you should not have a cheat day.

I'm not sure of your numbers and what kind of a cut you are doing but most of us here are doing 10-15% which ends up being a less than 1 pound per week loss. My losses are half a pound a week so if I start adding in a cheat day then my losses will be next to nothing.
