This one is clearly not in this category.
But as most self-help books, guides and sites, or assistance groups such as AA state that every little step helps, here's today's revelation:
shortly after colon surgery, artichoke is not a good idea!
It's proven stronger than me, and although eaten at lunch, it was happily making sure i was aware of its progress in my digestive track all through the night.
Note to self: don't try again before a few months.
