I know its not likely to be the sole cause, but could it possibly be TOM approaching? Its actually very appropriate you wrote that considering what I've just been through. Everyone - Have you considered how you are going to approach 'maintaining'? Its something I've tried to do many times in the past and I've always failed (otherwise I wouldn't be posting here!!!!!!!). I've now got to a stage when I don't think overweight or formerly overweight people have 'normal' metabolisms in the accepted sense and we have to approach our post-diet life differently. The problem is.... how?
This time I started off at my highest ever weight and its been more of a struggle to get rid of it than it has been in the past - but, if I persevere, actually losing the weight has a forseeable end to it whereas maintenance will go on for the rest of my life.
In the past I've tried a) mentally keeping a rough track of my calories on weekdays and 'eating normally' at the weekends or b) attempting to slowly increase my daily calorie allowance until I'm maintaining rather than losing. Neither of these have worked for me so I'd be really interested in how other people are intending to cope with maintenance.
Sorry to be depressing but I've just had coffee with an acquaintance who I haven't seen for ages. The last time I saw her was about a year ago just after she won her slimming club's slimmer of the year prize (she lost half her body weight) and since then she has put back on ALL the weight she lost plus some more. She was so upset because she doesn't really know why. Its made me feel very panicky.

Yeah, well I could say I did that because I was trying to "maintain" but there's something about being with my parents that makes me want to eat and eat and eat. I think it's something about being put on a diet, but now I've lost it my way and I'm in defiance of my mother's "diets". So I like to be, "Look how much I can eat right now - and I'm slim" Of course, you see why that's flawed...
It'll be ok in the end! I'll let you know how the rest of maintenance month goes!
However, stuffing your face like a
is not! 



and perhaps the gym at lunch or a run before kickboxing or both or something!
Take care of yourself. I like ginger tea when I'm feeling miserable - it clears out your sinuses too! 
Mushrooms!
