Are there any good ways to prevent migraine?

[*Laurelindo*]

I've realized I probably suffer from migraine, because a few times a year (luckily not very often, this is my first time this year) I get a random painful headache combined with a huge dizziness and nausea, and just standing up is extremely tough.
Usually I manage to get rid of it later in the afternoon by drinking lots of water, taking aspirins, eating and resting - but are there any ways to actually prevent it as much as possible?
I mean it's not quite as much of a big deal for my life quality as one might expect (I always consider every migraine my last one and then just kinda forget about it), but it sucks like hell when it does happen.

And yes you guessed it - I had a migraine today and just got rid of it.
