How many pieces of Candy are you going to eat???

I am excited for Halloween (the dress up, and stuff like that will be super fun), but I don't so much look forward to the candy part (or I do, I just don't usually look forward to the consequences of eating TOO much of said candy in one sitting...).  So, the question is, do I allow myself to eat some candy on Halloween???  Or, do I just watch everybody eat to their heart's content, as I sit back feeling left out and alone????  I don't know.  What do you think?  I will probably allow myself a few pieces, but then, where do I tell myself to stop?  2? 5? 8? 20?  I don't know.  I know if I don't allow myself to have some I will go crazy and then start binging on a ton.  So, I just need to control how many I eat.

What are you guys doing to fight the temptation to eat the whole bowl before the trick-or-treaters come to your door (or car trunk in my instance)?
