I hope you've pooed!!

A small bowl of prunes, with a glass of warm water with fresh lemon juice.

Keep a container of prunes in water in your fridge, so they soak up lots of water, I found it makes them work much better. You can drink the water then too, which also is good.

Some people get flaked bran and add it to their cereal, or just pop some in a glass of water.

And psyllium husks are also good. You can get them from health food shops.
