I think I've seen agmatine help with ptsd but I did not like it personally, gave me brain fog, just made me stupid.
15mg pregnenolone sublingual before sleep eliminates waking rumination, its a neurosteroid (I just buy 50mg capsules and pour some out)

I was eating a lot of choline and then taking/eating things that were inhibiting its breakdown. I was stuck in doom/hypervigilance.
