I do not get nocturnals from gluten but gluten makes it far worse, I stay away as much as I can though I love a fresh favorite loaf of mine occasionally. When I consume gluten it mimics the POIS issues to an extent but not completely. I get more mentally foggy, a bit more slow but that's really it. The next day if I get sexually aroused I can "leak" more easily due to it somehow whatever is going on there which feels disgusting but there is no way to control it. I only had a nocturnal onceand it was when I quit kratom for a while during a withdrawl with a sexual dream, probably previously only ever happened once or twice in my entire life so they're very rare for me.
