That only works if, unlike me, you actually have the self-control not to just eat the whole packet... :(

I haven't done it in a while, but I used to buy a cigar -- inexpensive yet inoffensive, such as a Punch, a Romeo y Julieta Robusto, or one of those handmade wonders from Leon Cigars in Koreatown -- when working towards a draft. I'd keep it to hand, almost like a totem or a good luck charm. Once the draft was finished, I'd step out into the front yard and fire it up, pondering the distant search lights of Hollywood and Vine.

Not as a celebration of completion, I should add, but as motivation. Something to work toward.

I'm a big proponent of this idea. But to stop myself turning into a four hundred pound blimp, I keep a cupboard full of rice cakes, oat cakes and crackers. So I'll write for an hour, run downstairs for a glass of sparkling water and a couple of rice cakes and maybe an apple, munch on them and then get back to work. It helps break up the day and keeps energy levels up too. On another note, if I'm stuck on a part of the script, getting out for a walk or doing mundane gardening work will always, without fail, help to un-stick me. I think it might have something to do with the mundane, ordinary task occupying the front part of the brain, thus freeing up the deeper part that deals with ideas and creative things.
