Migraine attack.

Recently I have been experiencing the migraine attack. I can tell you that the pain is very terrible. Before migraine attacked me, I experienced a glaring vision, not long after that I feel a terrible headache. The headache attacks one side of the head only. As for my case the headache will be followed by vomiting. What are the things that I need to do to avoid the migraine attack? What are the food that I need to avoid and the food that I need to take in order for me to avoid the migraine attack?
