Double migraine

I woke up in the midst of a migraine aura on my left side which meant I was going to get a headache on the right side of my head. I took my medication and tried to ignore it. Now as I check email and the weather on the computer, I find myself in the midst of a migraine aura on my right side which means that I'm going to get a headache on the left side of my head. I suppose it's safe to drink some caffeine as I don't have any other sides of my head to cause a migraine on.
