This was a weird one.  I woke up with a sinus headache, used some Breathrite saline nasal spray and BAM 15 minutes and I was on the way to a full blown ANAPH.  Took all my meds and emergency meds and went to bed.  30 minutes of waves went by before I felt myself again.  Anyone ever have this before.  The sinus headache could have set it off too, but that would be new as well.
