Migraines and me

Migraines feel almost constant, diary reveals have them at least 4 days from 7,  pre 2014 used to be intermittent. Cannot have beta blockers as they caused asthma now have for ever, am already on nortryptaline for sleep disorder, this year under GP have been on pizotefen for 3 months then topiramate for months, now off all preventatives awaiting neurologist next February. Have cut painkillers to absolute minimum as they do little for pain really and exacerbate grogginess....nightmare!
