I’ve always wondered how people can sleep with pieces of plastic in their ear…
@Ferdz I do it all the time. Due to PTSD, I used to have nightmares almost every night and by using earbuds, I focus on the audio which somehow blocks my mind from going 100 miles per hour and therefore, now nightmares are few and far between. Plus, the newest sleep models make them so much more comfortable to wear all night so I never go to sleep 
without them. 
Glad to hear that you have recovered from your past problems!
