This is a very a good habit to get into. To clear one's heart before sleep is like removing crap that is just going to rot overnight. No wonder one can wake up fresher this way. I have been practicing this for sometime now but once in a while I forget and the following morning I can literally feel the emotional heaviness. Good going bro!
I usually don't add water over fruits but hey, we all have different tastes. I hope you enjoyed the snack!
