Yesterday I was drained very badly and I have no idea how I got drained. I fell asleep at 4 in the afternoon and woke up about 12 hours later when I felt really good. As soon as I started getting up though, I started to shake and then started to lose body movement and such I tried and put as much force to get me out of it. I was finally able to resist. I have no idea what happened. If anyone could clarify for me what it was because it happens every now and then and I have never actually had a seizure in my life as I am also healthy and no head injuries. Nothing.
