List of substances that cause crashes

I’m looking for help from the hive mind here. I want to put together a list of known substances that have crashed people, or that are risky. Pharmaceuticals, supplements, foods, other, etc. I think this would be helpful for members new and old.

I personally am tired of explaining my condition to every new doctor I visit and would just like to be able to put a full list of medications in the “things I’m allergic to” list. Antibiotics, antidepressants, and others. I’ve read so many over the years in different posts, I’d like to compile them in one place. Maybe this has already been done, and I just haven’t seen it. I’ll start with some most all know, and

Finasteride
Saw Palmetto
Pregabalin
Flax seed
Pumpkin Seeds
Creatine
Wellbutrin
SSRIs
Isoretenoin

For me carotenoids and antioxidants cause crashes
(zeaxanthin, lycopene, beta- carotene, anthocyanins itp.) But I don’t know how common it is to crash from those substances.

I saw crashes from ALCAR on this forum. Phthalates and PFAS can also cause this,
I would also avoid sulforaphane and goitrogens.
From what I’ve experienced vegetable oils are also bad.

As for things outside of food/supplements: any head trauma is bad because it affects neurosteroids. Hard cardio also caused a crash for me when I tried to get back to boxing.

Whatever you do not use a device like this in your mouth
