Recently I returned to college in my 30s after battling a childhood sleep disorder and I now discover staying awake might be the least of my troubles. Now that I failed a few classes I'm trying to analyze and overcome the causes of this recent disaster. Two things are obvious. First, it takes me way too long to complete tasks (as if suffering from time dilation) tests take me approximately twice the amount of time to finish[and the amount of time it takes to study and do homework is cumulative and unsustainable]. Secondly, I just can't seem to remember a whole lot. I know sleep and memory are very closely related, perhaps that's why I have never been able to commit the times tables to memory. my research in the subject of memory has not been very fruitful, therefore I want to ask/Slashdots for input into which angle/direction I should look into next. As for cognitive speed I have completely drawn a blank."
