My diet is incredibly healthy and I drink well over a gallon of water per day. My diet has also been very constant over the past 6 months, so I don't think this is the problem. I stay away from any foods that are known to be associated with headaches (ie, chocolate, peanuts, caffeine, etc). I think I would be content if I got one migraine per month (although none would be great :)). Thanks for your suggestions though.
Well, Books-a-million doesn't have the August issue of Discover yet, but I'll keep checking back. I'm really interested in what they have to say about the subject.
The muscle relaxers I've been taking seem to be helping a bit, but I still feel like I'm on the edge of a migraine every day. Maybe some stronger muscle relaxers are in order. Right now the ones I'm taking are very mild (Skelaxin). I've also been taking some ocular nutrition formula in case the problem is with my eyes, but I haven't noticed any large effect. I have photosensitivity problems, but they are often a side effect of migraines.
Thanks everyone!
