I need your advice. Yes, YOU!

Ok, I don't care if we have never spoken before, but I need some input on this.
Because I am actually totally unable to make a decision and stick with it on my own.

I have been trying to stick to 1200cals per day for a while, sometimes going over, sometimes staying under.
Exercise has been a bit inconsistent, except for the last week or so.

Weight wise, I lose a bit, I gain it back. I lose a little more, I gain it plus more back.
Confuses the hell out of me.

When I was eating as little as possible, I was pretty much losing 0.1kgs every day, fairly consistently.
Every now and then I would have a bad day and binge, gain like 0.8kgs, lose it, and keep going.

SO.
What I would like your advice on, is which way to go?
It would be really great if someone could give me a hand with this. :/

At the moment, I'm leaning towards option B, but I know, it's unhealthy, it can't last, yadda yadda yadda.

Anyone want to help?
