Getting to sleep habits

[Lakie]

Having a chat with.a bunch of people last week and we somehow got onto the topic of things people have to do to get to sleep. I mentioned that my wife is heavily pregnant and as a result snores really loudly, as a result ive taken to putting on a youtube vid of rainforest sounds through earphones to block it out, I thought that was weird but apparently its not uncommon to have things like that in order to get to sleep.

So, anyone got any quirky habits like that? Have to have fan, tv going etc?
