I struggle with going to sleep and have tried myriad methods of falling asleep. One of the best ways was to plug in my iPhone headphones and listen to a documentary on Iplayer or TED.

However several months later a huge problem occurred. Both my ears were infected, left moreso than the right, that caused me a great deal of irritation and pain. Many months of visiting doctors, hospitals and medicine did this horrible problem get better.

Bear this in mind even though I was using dettol wipes to disinfect my headphones daily!
