Attacked again

Can't seem to figure out what's really the trigger for these migraine attacks. Puked out the bulgogi I had for late lunch (ah-ha..late lunch one reason) last night. I knew I had to let the meal out. Ate the caffox tablets..had lain in bed..waited for the pain tto subside..and yet I could feel the bulgogi percolating inside..yet undigested after more than four hours.

Caffox -Rm6/7 satu papan.. there's another generic (Cafergot)

same contents but don't seem to suit me.
