LCHF week 3

The third week I actually went a little up on weight, I weighted 74 kg. But I had my period, so I don't know if I just was bloated because of it, and when the period goes away I will discover that I went down anyways.
I made a nice discovery then: usually the week preceding my period I had the worst cravings for sweets. It would be always in this week when I would indulge. Not anymore. I had no cravings at all!
Also I would get terribly moody and angry. I am quite sentimental now, but not angry. My boyfriend is welcoming the difference :)
This week I developed a routine. What is tough with lifestyle changes is that all the usual rituals around food are gone. I used to have oat porridge for breakfast. Made without sugar, just water, milk and oats, till it became thick. I made one big pan and then put the mix in small Tupperware containers to heat up later. From the perspective of the calories it wasn't too bad and it kept me going. But from the perspective of carbs, it was a lot. What to eat now then? Now I have 2 boiled eggs. Sounds little but actually eggs are quite filling.
One of the biggest drawbacks of this diet is that you cannot deviate from it. It is really not advisable. One night we invited some friends for dinner. We had the usual LCHF fare: a piece of red beef with mashed broccoli with cream and cheese and a salad of tomatoes and avocados. For dessert we had raspberries with (unsweetened) cream. Delicious.
But the following day I was craving sweets again. I suppose it depends on your metabolism, and how sugar-addicted you are how much it affects you. For me it is very strong. A tiny bit of a sugar-ish thing and I am pinning for more. 
I am so happy on this diet that it got me thinking. I am following this diet to go down on weight, but the diet is not sustainable. To spend life never going to restaurants, never eating at friend's houses, it is just not possible! My plan when I reach my desired weight is to go in and out of it. Follow the diet a few days in a row and then eat some carbs. It will be difficult I think. But what this diet proved to me is that sugar is strictly off-limits. I am a sugar junkie.
