The only thing i can suggest you try for now, is to inhale
deeply through your nose for 15-20 min's. another thing you
can try is get some ice from your freezer wrap it in a hankie
and apply it to your temple, the top of your head and the
back of your lower neck.                                                   
Hoping you find some relief.                                                      

Hoppy.

My emergency aborts:

Sugar Free Red Bull, chugged at the first indication of an attack.

Hard, cardio exercise that pushes you to exhaustion, wind sprints, squat jumps etc.

Bury your face in the freezer or in front of a car AC vent and hyperventilate drawing the cold air through the nostril on the effected side.

Drive to the pharmacy now and get some Melatonin, pop about 12 mg 30 minutes before bedtime, many can avoid the night time, wake up hits with this.

NEVER EVER EVER EVER EVER GET CAUGHT UNPREPARED.

EVER

I know it won't help you this go round but CH is a lifetime ailment. It ALWAYS  comes back. Never delude yourself into thinking it's your last cycle. ALWAYS  have a supply of whatever your prevent is, and whatever your abortive of choice is. It's essential you be your best advocate.

Wishing you some peace and pain free time soon.

If you can get yourself together long enough to go out and get some energy drinks (taurine is a must) then that would be my suggestion. You could also start taking high dosages of vitamin D3 (you can read more about it on this forum), though that will probably take a few days at least to start seeing improvement.
