Before I read your first post Lindor I was about to make a suggestion that you ban either Pringles or Tim Tams until you feel you can just eat one or two, and then leave the rest of the packet in the cupboard.
I noticed you haven't put your weight up in your signature for a couple of weeks now, but you said you've gained. This doesn't make you a failure - it means you've had a couple of ordinary weeks in an otherwise very impressive journey.
Maybe it's a good time to try and take some of the pressure off yourself - and take some time out to reflect on the journey sofar, and on the positive changes you've made to your life. And maybe it's a valuable thing for you to make 80kg a personal project. Never mind anything else right now - just sit down and work out a plan for getting to 80kg, and a timeframe for getting there.
As you get closer to goal it does get more difficult to lose each kilo - and it is slower. But maybe this is the part of the journey where patience and determination come into their own for you.
How much fibre are you getting in your daily diet? How many grams of fat? How many serves of fruit and veges?
Maybe it's time to make one radical change. What would happen if you got up an hour earlier, went for a 40 minute walk and served yourself a yummy high fibre/low fat brekky after that? Somehow I think it's important to find a different way to make a commitment to the 'new you'!
I don't know mate - I'm just throwing up ideas to try and help you out.
There's also a small chance that you've reached the stage in your weight loss where you're going to stall UNTIL you face the emotional baggage that got you here in the first place. No matter how much we all try to avoid it, it get's us all! I'm very close to that point myself (if not right in the throes of it, and trying to pretend it isn't happening

).
Another thing I do when I am stuck is convert my weight to pounds, and then set a goal of losing ten pounds. Sometimes it helps.
But don't you dare give up on us!!!
