you really shouldn't be driving if you have epilepsy. i am on the same drug but 300mg and i'm 18. i'm not allowed to drive by law because of my epilepsy. in Northern Ireland you have to be fit free (i don't like the word seizure sorry if it causes offence to anyone) for a year, i think its the same in the rest of the UK but can't say for def
if you are not taking your tablets and it is causing fits, personally i would think of upping the dosage to last you a bit longer but that is my personal opinion and not a docotrs opinion so please don't take it as a doctors proper medical opinion.
i was told to take my tablets in the morning because it can cause sleeping problems because there is something in it that can keep you awake and no sleep can cuase fits. i have a pill box with the days of the week on it so i know that i have taken my tablets everyday, you could maybe invest in one and keep it by your bed, that way if you are in doubt you can double check and take it right away.
if you thro up your medication you should taek more straight away and ring your docotrs surgery when it opens, thats what i was told, again i'm not a doctors so please don't say that doctor told you too.
that is all i can think to say. I AM NOT A DOCTOR SO PLEASE DON'T TAKE EVERYTHING I SAY AS LAW I JUST SAID MY PERSONAL OPINION AND THINGS THAT I HAVE BEEN TOLD!!!!!!!!!!!!!!!!!!!!!!!!
(again i am sorry if i caused offence to calling seizures fits i know that some people do find it offensive and i am sorry)
