Re: Am I going to die....
Make sure you are hydrated, have some amount of blood sugar and aren't on any excessive stimulants. But if it is a case of exercise induced migraines, the various Nitric Oxide supplements may help. I have a client that gets exercise migraines and nothing seems to help except the Nitrous Oxide vasodilators. I think NO2 is what he specifically uses and he says that it works wonders, but they are a bit pricey. Ginko, ginseng and yohimbe may help also.
