Heya,
Well yes, that is the obvious one. A shower or even just a bit of exericse after the edge can help just deal with some of the hormones flowing around that are keeping you awake.
It often does get easier, or at the very least gets easier at some times in the month. So do try some things, and see if anyone else has recommendations in the notes. But sleep is important and if you’re seriously missing out on it due to your edging then you may have to keep night time ones as a special event and focus on morning and midday ones.
