Is not medicating EVER an option?

My neurologist *thinks* I am having seizures. I say *thinks* because he is not certain, and 3 EEGs and an MRI show nothing abnormal. My episodes have been occuring 3-4 times a year for 13 years (as long as I remember) and have not changed in that time, other that becoming more frequent in both pregnancies (about 2x month). I do not lose conciousness, they begin with deja vu and then a general feeling of "hey I've done this before". I get a little queesy, and after I feel like my head was squeezed and then released. They last less than 1 minute and I am able to talk, drive, read, and even teach a room full of 11 year olds without anyone knowing what is happening. I asked my OB about it this pregnancy, she sent me to the neuro, and the tests ensued. NOW, he has decided I should go on meds "just in case". Now, my sister has seizures as the result of a head injury and I have see what the meds do, but I have also done my own research, adn talked to other seizure patients so I know I'm not over reacting to the side effects. They aren't peachy. So, why is my doc acting like saying it is inconclusive and I should follow up anually to see if things change or progress, is not an option? I KNOW, in my case, that the risks and proccess of trial and error with these meds is worse for me than the episodes, but he just thinks that is the craziest thing ever. So, is it just him, or is not medicating EVER an option? Especially with the negative test results. Thanks for any input.
