I'm prescribed to 2 different dosages of sumatripan. I try to take the lower dosage one as soon as I get any symptoms related to a migraine. If i take it right away, I can often prevent it from spiraling out of control. I keep the higher dosage ones for when it's at it's worst. I also make sure that I've eaten something that settles the stomach, just in case I get nausea. You can also get these one-time use ice packs and carry them in your purse. If I'm in a situation where I can't get home to a dark room right away, I like to use one on my neck/head to cool me down. Using cold temperatures is something I learned in therapy that helps regulate your heart rate, and it just feels really nice and gives me something to focus on. I also will put on sunglasses even if I'm inside so that the light doesn't make it worse. I also use ear plugs. Basically anything I can to tune out the world better until I can get somewhere safe. Hope some of this helps.
