I have slept badly for years and am used to waking up anything between 3 and 8 times in the night to spend a penny
. I usually manage to drop off to begin with, though, and after each loo visit I don't normally have trouble getting back to sleep. On the occasions when I can't even get to sleep in the first place I get up and have something to eat - crackers, or a slice of bread and butter or cake. It is definitely true that it's the carbs that help me to sleep. You'd think it would give me indigestion, especially as I suffer from reflux and heartburn (I've got a sliding hiatus hernia) but it doesn't seem to!
