My Wife Emily gets Migraines. Terrible ones. They control her life. We have discovered that they are usually linked to barometric pressure changes. The sooner you take your Imitrex (anti migraine meds) in this situation the better. I'm going to built a device that monitors the barometric pressure. If it changes drastically, it will set off an alarm and send a text to her phone, reminding her to take her meds.
