Here is anecdotal evidence for another interesting "drug":

In this study, N=small, but nevertheless, I think it is a very interesting article. Because the effects are so rapid, and magnesium supplementation is in general harmless, it is imho definitely a good idea to see if a magnesium deficiency is the cause of the disorder. Please take note that not all magnesium supplements are equal.

Technically, it's not a study. They present a few case histories, which is basically, "we found a few patients whose depression went away after taking magnesium, maybe we should look into it".

That being said, it would be pretty easy to investigate.

Anecdotal again, but if it helps anyone else - my SO used to suffer with regular migraines, but since taking daily magnesium they have completely gone away
