How am i supposed to not grind???

I recently started with nofap and pretty much instantly realised, there was a little problem.
I am sleeping on my stomach. When waking up with morning glory, as one does, how on earth am I supposed to not eighter grind the bed or even use my hand?
There is no porn or orgasming evolved, but I kinda still think, that isn't optimal and if so: how am I to not basically wake up with my dick in my hand?

thx in advance

 

Well first and foremost we all basically are animals. But thats not the point. As soon as I am fully awake, and my brain actually starts working, I sure am able to do whatever I want. but the point of the thread was to get some advice, on how to help myself realising, that I am being awake and in fact interested at living, rather than keep on dreaming.
Simply being told, that my problem makes me a lesser human, if human at all, kinda doesn't solve anything.
