swimming and epilepsy

Hi all I am a swim coach, in the water a lot teaching children and have just been diagnosed with generalized epilepsy. Im juststarted on sodium valproate and although the first two days were hard now its workinv awesome and I cant believe the difference. I am a completely new person now.i was havi g seizures daily , in the pool as well now I only get them if I eat sugary foods. Ive really lost confidence esp with being in water now I know all the horrific symptoms I was having is epilepsy. But also really lucky worse things havent happened while working. What sort of chance do I hav of having another complex ..unconscious seizure while on meds.....does anyone know? Not sure if I should find a new job that doesnt involve water.working from pool deck at mo.
