Practice makes perfect! Keep on showing up and it will most likely get easier :)
I currently do not do guided NSDR that much, but it helped a lot at the time learning how to calm my thoughts and become deeply relaxed, especially the Ally guided sessions (as everything else, takes practice) so I would recommend to try the guided ones even if it feels awkward, until you learn how to stop your mind from wandering. I find it helps both with quick reset/recharge naps and falling back asleep if I wake up in the middle of the night (happens often for me).
