I actually had 2 nights in a row with pleasant dreams.
Even though I wake up with my earbuds fallen off. Also seemed harder to fall asleep with earbuds as I'm a side sleeper and not used to sleeping on my back.
Phones seem to go from 100% to 80% battery. I was worried my phone was going to die and the alarm clock wouldn't sound.  But no worries. 
Going to test this for the 3rd day.
