What can you do to recover from classic migraine?

Be seen. There are many effective treatments for migraines. Often, by successfully treating a migraine, you are more likely to not have a recurrence. Conversely, if you fail to treat your migraine effectively today, it is more likely to come back tomorrow.
OTC remedy. Try otc (over the counter) remedies first (e.g. Extra strength tylenol), avoid triggers, if applicable (e.g. Noise, light, etc...) are some basic steps.
Magnesium. Magnesium 400mg twice daily try this first. Will need a liver detox to eliminate toxins. If you have fillings will have to do heavy metal detox with chlorella.
