I had a brilliant photographic memory all my life, then lithium came along and destroyed it... Sometimes (when i'm hypomanic) it kinda makes a comeback... Concentration? I used to have quite the concentration span. I could literally study 1 subject for 4hours (before i give in to hunger or a cigarette) these days? Uuuuhm... Not so much. I have to concentrate on concentrating, and let's not talk about when hypomania comes to town... So i guess what i'm trying to say before i rambled,is that for me it seems like a mixture of the 2 beasts, it's their freaky hybrid offspring thingymajiggy...
