When I say potatoe chips my mouth waters. I think it's a salt craving. I've tried to substite the urge with pretzels...but it just isn't the same thing. I'm amazed, eagle, that you can eat only a few chips. When I start, I can't stop, so I try not to start.
Chatty, when I read your craving, I thought of the song Polly wolly Doodle all Day. I sing that with "A" all the time.

"Oh I eat watermelon and I have for years
Sing Polly Wolly Doodle all the day
I like watermelon but it wets my ears
Sing Polly Wolly Doodle all the day"
