Thanks Kitt. I'm really scared here as I don't know what's going on now, when it happened the first time or the second either. I literally haven't slept in 7 days now, but what worries me most is that there was no brain shake episode to trigger it this time. I don't even feel tired now, but wired. I tried researching on what's wrong with me, but my concentration and memory are so bad from the lack of sleep. Even when this happened before, I slowly got my sleep ability back. I never just crashed.
