Seizure after 16 years

I used to suffer from Epilepsy when I was 14 yrs old, I had a 5 seizures within 1 yrs time. Since I was 16 I didnt have any further seizures, until this May. Since May I experienced 3 seizures. My epilepsy has been controlled my medication and I was also driving (which I have stopped after 1st seizure). Is it common for epilepsy to come back after such a long gap? Also, I have bene suffereing from dry / red patch around my face and neck. Are these reletaed by any chance? I feel a bit traumatised as I was beginning to forget I even suffered from this disease.  My sleep patter in good, I take medicinine on time. I exercise.  Does alcohol compumption makes it trigger? I drink very occassionally.
