Hello, Rafals! And welcome.
To answer your questions Ducki, I'm keeping an eye on my calories on MFP, but this is because I have the time and am not sleep deprived! It's much easier being 'good' when you have a decent amount of sleep and your sugar needs aren't bouncing all over the place. So cut yourself your slack on your will power. You aren't to blame on wanting a perk.
I also have a big appetite, and could eat carbs for England, so I find that upping my protein (boiled eggs are good for this, cheap, quick, low cal) quells that carb addiction quite a lot. So lots of chicken, tinned tina (with a SMALL spoon of mayo it goes a long way, esp on a big salad).
I am eating the same stuff as the family (fuck cooking three dfferent meals), but eating a smaller portion with more veg. I am avoiding wine for now as this is my undoing; not just the wine calories, but the sod-it calories, the next day mop-up calories and it also really disrupts my sleep (and you know how that feels).
I'm not worrying too much about exercise for weight loss, as I will do this whatever my size (esp swimming). It's more for my mental health (I'm studying f/t so need fresh air and screen breaks!).
