Hey Harris!
Welcome! 
From my own experience my cycle changes randomly though mostly I experience it during the long, dark months of Winter (once I had them in June but I was spending a lot of time indoors in a dark setting).

I think other folks will chime in and tell you the same thing:  That the beast can change unexpectedly.

Take a look at the information at the left side bar under "Oxygen Info."  O2 is a safe and very effective abortive that you might try in addition to (or even in place of ) the Sumatriptian.  I used it this past cycle and was able to minimize my usage of Sumitriptan. I was pleasantly surprised that I could knock out the beast within 10 minutes (if I got to the O2 ASAP).

I'd also recommend looking at the post titled "123 days pain free and I think I know why." A number of us (myself included) have benefited from the vitamin D3, fish oil, calcium, zinc, magnesium supplement regimen listed there.


Here's hoping you have a long remission!

Hi Harris!

I basically just agree with what the other 2 guys said. 

You're a smart feller for doing some research here between episodes, when everything isn't a big emergency crisis.

I would suggest having an arsenal including O2 all planned for and ready to implement (and a plan B!) in case the beast comes a knockin' again.
