No you're no wuss at all. And I don't think it has anything to do with your dislike of the dark. But now that you say, "...it has increased in frequency, particularly last night when it occured 3 times in the space of an hour,..", I would definately see your doctor about it. Don't be the least bit embarrassed by it. And don't be afraid to see the doctor about it either. It might just need a bit of medication, or maybe not. Good luck to you.
Hey sarah thanks for the advice but it happens very rarely and for one point didnt occur for nearly a year, i always put in down too me being a big wuss who doesnt like the dark so this is why i beleived it would be a waste of my GP's time!
