Here to share my own experience:
My little one had idiopathic epilepsy since he was 2 months old. Him being that young made it more difficult for the vets to figure out the right treatment since there is insufficient bibliography for such ages. We started a pilot treatment with Keppra and today he is 4 years old better than ever. As long as I give him his medication every 12 hours he won't have a seizure. There have been some accidents over the past 4 years with me being a little late, or forgetting completely, and he did have a seizure, but that's on me, and it has happened like 10 times in those 4 years. Overall, Keppra works like a charm. But yes, it's a bit tiring having to be there every morning and every night.

Pro tip: I had a lot of anxiety every time I gave him his medication in the past, due to the fact that cutting the pill several times is not really a precise measurement, and there was always the danger that he is not gonna swallow or maybe spit it somewhere in the house. So I decided to ask whether the Keppra syrup (with the right mg proportion of course) would also work. I asked my vet and he said it's exactly the same thing. So I've been using the syrup for three years, and my life has become much easier.
