Epilepsy help

hello everyone, i am 22 this year, male, malaysian. The first time when i have this issue is when i am 13-14, where i stay up until 4-5 am, my body will jerk for like one or two second, at that time i have no idea why it happens. Until i am 15, there was once i stay up till 4 am, the next day when i wake up and i play computer, the next moment i am on bed, i have lost my concious and seizure. And it dont happen often, usually until i sleep late at night, but it varies. Until last night, i thought i am okay because it dint trigger seizure but just jerk like few time in almost a year. The last 3 day, i am at malaysia genting, watching Dota tournament. For first 3 day, i sleep at 2-3 AM, last night, after tournament, i went to casino, until 4.30 and having lemon tea, when i am back. While i am on the bed, i couldnt sleep. When the moment i am fallen into sleep, my body jerk and i am awake. And it keep repeats. But if i dont sleep, i scared that seizure will occur, so i keep try to sleep. When i am awake, my friend show me his hand and fingers, i bited him, he told me that when i tried to sleep, my seizurd happens. 1) What type of epilepsy i am having? exposed to repetitive lights and sleep? or lack of sleep? or lack of water? 2) My liver feels heaty yesterday, is that partial of the causes? 3) Like yesterday, when i am sleeping, but my body keep jerk, in that case, what should i do? Btw, i dont take any medication as my parents worried that it may causes side effect like if one day i don't take i will be unable to control it. Any help for me? Thanks :)
