I had a period of dreadful insomnia which came out of the blue and went on for a couple of months. Since then I am terrified of insomnia, well terrified is a bit strong but I really get upset if i can't sleep and get all worked up which of course keeps me awake. Anyway for past 5 years I haven''t really had a problem but the odd night, literally a few times a year, I can't sleep at all and can stay awake until 4am or something silly before finally dropping off or even not sleep at all one night. I am surrounded by people who never have trouble sleeping. So am I BU to expect to sleep well every night or is the odd sleepless night normal?
