Hey there
Firstly, you
can conquer this, honestly, you just need to find a way that works for you.
Secondly, I LOVE Arabella's willpower switch idea - that's awesome!! I'm definitely going to be trying that one today!
Thirdly... a few years ago I did a workshop that helped me look at so many of the reasons that I overeat, and also helped me with getting a few ways to combat. It's kind of a process (and lots of the steps have been mentioned before!) but here are the steps that I use, in case they can be any use to you at all...
1. I wait 10 minutes, and see how I feel then. Can I wait another 10 minutes? If I can, I do. Repeat. In the meantime, I ask myself if it is really hunger that I'm feeling. With me, I find often it's boredom, loneliness, frustration, or procrastination. If I can identify something else that I'm feeling, it becomes much easier to address that, and then the eating becomes less important!
2. If I decide I absolutely have to eat, I take a minute, just one, and really think about what I want to eat - often I find that I instantly assume I want chocolate or something cakey, but actually if I take a moment to really think about it (hot or cold, sweet or savoury, creamy or tart etc) I usually want something really random, like cheese or even (gasp!) veg!!
3. Once I've decided what it is I want, I take a small portion (like a couple of bites - if it's something like biscuits, one, if it's crisps, 2 or 3 etc), put it on a plate and sit down at a table. I turn off all radio, TV, close my laptop etc. I try not to do anything else at the same time. I just FOCUS on the experience, the taste, the texture etc. This is NOT about hating yourself for doing the eating, but it can really help you combat mindless eating. I know myself that I can go through biscuits and the like without even really noticing if I'm watching the TV or something at the same time, and then I feel guilty and unsatisfied. I know I read that you have a 16 month old, so this might be really difficult, but I think the point is just to make sure that you're really experiencing what you're eating, and not just shoving it in your mouth in between other jobs. If you really want the food, enjoy the small portion that you're having - you'll probably find you'll be satisfied with less.
4. When I've finished, I wash up my plate and put it away. I try not to just put it in the dishwasher, as I can too easily get it out again!
5. If my hunger is still not satisfied, go back to step 1. Repeat.
These steps have really helped me - I hope they help you too. The workshop I did was by a company called Beyond Chocolate, they have a book as well - you can google them and they're on Amazon. I totally recommend it (and no I don't work for them!!

) - PM me if you need any more info!
Lots of love
