When I was a kid, my Grandmother kept "snacks" available. She had this "candy" that was made with Soylent Green and some kind of sugar/syrup shell. If I wanted a snack, she'd break off a chunk of this stuff. As it approached my mouth, I could feel my taste buds attempt to burrow down under the surface of my tongue. Unfortunately, they couldn't run far enough.
To say that it tasted bad is a gross understatement. Bad doesn't begin to describe it. The English language does not have words to convey the nature of the flavour. Horrific, Disgusting, Putrescent, and Vomitous don't even scratch the surface. It was the sort of taste that makes you wish you had eaten your own head instead. It made the prospect of diving face first into a pig sty sound yummy. 2 week old, spoiled Haggis? That would be a wonderful improvement.
After a couple of bites, I regretted that I had ever learned to eat solid food. After a couple more, my stomach attempted to flee from my body. I couldn't blame it. I only ate another three bites. At that point, I could hear colors and see the number 19. I didn't have an out of the body experience, but I wished that I had. I don't think I would have gone back.
This may not be the best way to attempt to curb snacking...
