I thought I could deal with the fun-size candy bars, but learned the hard way that I'm not there yet. Hopefully, I will be some day.
I'm now thinking about giving out gum as a treat. Gum won't be tempting to me at all, and I won't feel bad throwing out any leftover gum. My DH tends to buy too much Halloween candy because one year (in 22 Halloweens together) we ran out, and had to use our kids' stash. It was so traumatic for him that he's been overbuying ever since. At least that's the reason he gives! In the past, he'd take any leftover candy to work, but he telecommutes now so there is no place to take leftover candy.
Last year we got two groups of kids--about 5 kids total--and had lots of candy left over. I had just started WW, however, and had high motivation. I'm almost a year into it, though, and the motivation isn't as great.
I'm curious how others handle Halloween??
