I appreciate very much the replies to my post last nite.  It was a very rough nite, 1am-415am, nuff said.  The O@ co. hasn't got me regulator yet that works, although they're supposed to be on their way.  So my O2 therapy should start tonite.  My Dr. never has mentioned injections of Imitrex??  I've never specfically asked because I didn't think it was...Idk?
I'm still breaking pills in half and trying to figure out if it's worth it to pay the $200 Walgreens wants for 6 inhalers.  I have alot more knowledge and focus on this now that I've found this site.  I need the injectors.  I will also try melatonin....thanks again for the support.

I am an Imitrex Injector user but since figuring out 02, I only use trex when I get caught away from my oxygen tank....which I assure you on cycle is pretty damned rare!

If you do not get a mask by tonight do the following:

Take a 1 gallon freezer ziplog bac. Cut a small hole in the bottom, insert tube from oxygen tank into bag, tape the crap out of it so it's more or less air tight. Ziplock the top shut, poke a slightly larger hole near the top of the bag and stick the cardboard tube from a paper towel or toilet paper roll in and tape the crap out of it.

You are now the proud owner of a non re breather mask. Turn on the 02 watch the bag fill, put your lips around the tube get you a big old lung full, remove mouth to exhale as you do not want exhaled air back in the bag...(non re breather)....suck on tube again ....repeat until headache is gone.

I'm 50, episodic for 31 years. I have been using oxygen as my primary abortive for over 20 years. Has radically changed my life and how I face the beast!! Hope it does the same for you.
