Have you gotten a headache from CBD oil?

I tried CBD oil earlier today and honestly it did nothing for my chronic pain.

(I don't smoke or take medicine because well, I don't like the side effects and my body is quite sensitive to medication.)

Anyways, I took a few drops because my friend swears by it. Within an hour I'm having a pounding headache (I almost never get them.) and I'm having horrid bubble guts. Nothing is new in my diet or daily life besides the CBD I tried.

Has this happened to anyone?
