Personal experience update:
Nurtec was effective for the first 24 hours or so, but didn't make the 48 hour goal.
Last night, within the 48 hour window of initial medication, the first visit of the beast came at the usual 1:30 AM time. I think it was not as intense as usual. Pain only, no rhinorrhea, conjunctival injection, or lacrimation, and I spent 10 minutes on the tank before heading back to bed. Normally I'll get three visits during the night, but I'm on the tail end of my cycle right now, so I can't use the reduced attack count as a guide.
So maybe it still had some kick left in it? Not sure.
Tonight I'm going to wait for the beast before medicating, just to see how fast it actually works.
I probably won't update again unless something radical is noticed. I'll keep using it for the next couple weeks till its gone. Bottom line for me is, if insurance doesn't cover this it's a moot point. Sumatriptan is faster , cheaper and much more predictable, oxygen is a good backup.
Considering the retail cost, I'm disappointed in my results so far.
