What medication to choose? Effectivity vs side effects, please help

I only have 10 minutes every 5 months to talk with a neurologist that seems to be operating a machine, so I decided to come here, you may help me and beforehand I say THANKS. To contextualize: I am 26 years old, diagnosed from focal seizures, absences epilepsy, since 12 years old when I got a grand mal seizure. I get 2-5 absences a day, some days (5%) no absences. Grand mal seizures have occurred in me 20 times approximately.. initially with an average of 1 year, now every 3 months more or less. These months I have been on 200 vimpat and 200 lamictal daily. However, side effects such as memory loss and dizziness made me want to change things. I put Tegretol but it has not worked, on June 20 I got a grand mal seizure and side effects have not gone. I don't know if returning to valproic acid, I don't know anything, the only thing I want is to say bye to absences and secondary effects of meds that give me real problems daily (can't get a job, forget things, etc, etc). I live in a constant apathy. I don't drink, don't smoke, sport on sundays and I have too much sex with my girlfriend and with myself lol.
