I've been on 300mg a day for the last 2 years. I think it's becoming less effective (although it is working - not had any grand mals for over a year)
Getting overly tired which I think may be a side effect?

I haven't taken it personally
but in general I know it's unusual to develop side effects after taking something for that long without problems. I'd suggest a trip to your GP just to check it out.
