For me, green vegetables seem to trigger nervousness and sleeplessness, when I still ate them, I'd wake up at night and think someone is in my room to murder me. I'd get up and wander through my flat, go pee, and sometimes it took like 3-10 Minutes until the feeling of somebody being there would go away. Been on an elimination diet and trying around for 5 years now, there seem to be some pointers towards SIBO, but I haven't managed to fast long enough to do the test yet. When I eat the wrong thing, it usually takes 3-4 days for any effects to show. Would make sense if it's fermentation or rot in the intestines that's triggering this. Hope you'll get well soon!
