Why do i only have seizires at night?

Several reasons: It is hard to come up with a definitive answer without more information. It is possible that your seizures are sensitive to light so if you spend time on the computer or tv at night, the flickering lights may precipitate your seizures. There are also some types of seizures that tend to occur more or even only at night (and are called nocturnal seizures). Some of these are inherited conditions.
