Is it ok to drink energy drinks for my condition?

I have had 3 cases of seizures a while back and I am not sure if it is a cause of not enough sleep or could it be the heat of the summer cause I've had them happen to me soon after summer ended last year and the year before, but I would like to know if having an energy drink will effect that cause I have a tiresome job that requires pushing, grabbing, pulling a lot and so what I'm asking is Would it be OK for me to have them cause like I said I am tired all the time and I hardly ever have any energy at work to get/ keep me going on the job and so any good advice will help me???
