I knit. It really helps. I am watching tv, but my hands are busy and at the end of it i have something useful to use/give. Can you knit or crochet? I also have a big pint of water beside me and make a deal "when i've knitted 10 more rows and finished that water i can have a biccie" - i never get to it. By the time i've finished the water and knitted so long i'm fuller and distracted so i don't bother.

For me i KNOW i will eat when bored, so i have to prevent boredom first and foremost. Sitting at a sewing machine, or with needles, or even drawing/painting something really mkes a difference. So, what is there you could begin to do with your hands that is interesting enough to stop you snacking?
Crossstitching?
Embroidery?
Knitting?
Crocheting?
Clay modelling?
Writing/typing that novel you should really start?
Painting and drawing?
Sewing by hand or machine?
Shelling peas?
Ironing?

Ok, not all very thrilling or exciting, but all needing "cleanish" process, so you can't be dipping in and out of the chocs while you do them, and all worthwhile in their own way.

ETA - somethin my sisters WW instructor of long ago told her - to have 2 sets of snacks made up in the fridge one for "hungry" snacking and one for "bored" snacking. "Hungry" had things like rice cakes, low fat cheese pre-cut into single servings, houmous, pine nuts and raisins, that sort of thing. "Bored" had celery, carrot, tomoatoes, spinach leaves, lettuce hearts and apples. It really helped as the higher fibre in the "bored" box stuff fills you up so fast AND is good for you, so it makes your bored snacking pretty harmless to your weight gain/loss.
