DAYS TWO AND THREE!
Well day one went pear shaped at around 4pm when I got miserably depressed, went out and bought a veggy 3 sandwich pack, 3 packets of crisps and a yoghurt and ate the lot. This would normally consitute the start of a binge for me - and 3 packets of crisps is clearly not good - first crisps i've had since pre-LL, I then passed out and fell asleep through jet lag - which makes it even more annoying - if I'd just allowed myself to fall asleep I'd have gotten through the whole day without eating.
So day two - yesterday I wake up with sabotage on my mind. I hit Tesco at 8:30am and bought SHIT LOADS of food - mostly of the bready, crispy variety. I ate a fair bit - but not all, and then threw up... 
However, I decided then that rather than starting the next day - I was going to start right there and then. So I put on my running shoes and went for a run around the park - just 2.5k. I carried on yesterday with a milkshake, a soup and a bar.
I've started this morning with a 5k run around the park and I'm feeling pretty positive. I slipped up and obviously 5 months of LL hasn't just erased all my old problems but I've drawn a line under it and I'm back on track.
I've been thinking about why I did it. When I came off LL pre-Japan I was on "management" and tbh I didn't exactly follow it to the letter, but I made sensible choices - by and large. Nothing was really forbidden anyway as I knew I would be eating freely in Japan, so I didn't really feel that urge to buy "bad" things.
The whole time during Japan, whilst there was chocolate and cake at times, by and large I ate ok, and more importantly I ate at meal times and was aware of what I was doing. I went running every second day, cycled more days than not, I went swimming a couple of times, I found a gym and went there too and I played tennis and walked loads. BUT - the minute I get back and suddenly EVERYTHING is off limits as I'm supposed to be going back onto foodpacks, the most ludicrous food becomes attractive - in huge quantities and until I feel I want to be sick!!
I always knew this was my problem but it really does demonstrate to me - once I'm off this for good, I'm never going to not allow myself anything again!! I CAN regulate my eating quite well as long as I don't get into the trap of not allowing myself something!!
Anyway, another few days hopefully and I'll be back in good old comfy ketosis.
Other good news - I was convinced I'd put on loads of weight but my housemate brought home some size 14 Warehouse tiny shorts last night (I didn't think I could fit into Warehouse size 16 even pre-Japan) but they fit!! So maybe I'm not as porky as I feel?
