"works perfectly for knocking out a migraine. 2 sublingual sprays and it does not get you high, you can totally function. I am so happy to finally find something that works!"
In my experience, often a 20:1 CBD:THC tincture or capsule is very effective in prevention. Migraines are much easier to prevent with cannabis than to treat.
In most cases, I suggest 15 mg whole plant CBD capsules upon awakening on an empty stomach
