Migraine sufferer's who smoke and have high blood presser.?

Is there a trier that sets off your migraine?For me last year it was bad weather.Last year it was the Hurricanes,I live in land and am safe from thees storms.We do have the occasional Tornado and Micro burst.Nothing like they have in Tornado ally.Yesterday and threw the night we had rain and thunderstorms,My blood presser sky rocketed,giving me the migraine.I was prescribed ISOSORB MONO. It al so gives me a Migraine and my doctor took me off of it.Lat night I figured I needed to bring down my blood presser and already had the migraine so I took one.My questions are how are yours triggered,What do you do to combat them,and is your thinking impaired during and after the migraine?Can they be triggered by the attempt to cut down on your smoking or quiting smoking?
