Just wondered about this. I am one of those unfortunate people who needs complete darkness and silence to sleep. The darkness is provided by blockout blinds, but the silence is sometimes harder to arrange! (Neighbours partying, birds singing at 4 am,etc!) I have recently resorted to earplugs on a few occasions - just the cheap foam ones. I find them really uncomfortable, but they do help. I am thinking of investing in some better ones.
Does anyone sleep with earplugs every night?
