I've been told that entonox works wonders for migraines, so if I ever end up needing an ambulance for pain-related suicidal urges* again, I'll hopefully remember to ask for some. I just hope the request would be well-received. Druggies don't scam for entonox, do they? *The migraine itself is not an emergency, but suicidal urges brought on by pain can be, especially if you've caught yourself beginning to act on them.
