Hi, I am suffering on epilepsy from last 14 years.I was taking Zen Retard 200/300(Carbamazepine control release) till 2013.But later on after consulting to my doctor I am taking Oxetol 600(,Levipril-750(liveteracetam - 750) and Frisium-5(clobazam). But I feel that I am losing my memory and frequency of seizure is more than when I was taking zenretard -200/300. It was 1 time in every 1.5 year to 2 year and now I am getting in every 2-3 month. can anybody please suggest what I can do on this scenario.
