Personally, I don't think it's an act. Everything he does is easily explainable by bipolar. He's lost too much, if it's an act it's a really stupid one. He could be not crazy and be Jay-Z level, y'all really think he's getting that many crazy sales?
The bipolar folk I've known couldn't control it that well, at least not at the peak. They would keep their mouths shut about the craziest stuff in the early stages unless they really trusted you, but when it hits full-fledged mania they couldn't hide anything.
I think Cam'ron is either just really bad at noticing the signs, or the timings of when he sees Kanye just aren't at the peaks. And however far gone Kanye is when he sees him, he's still present enough to hide it for at least a while.
Nah, bipolar folk are triggered into manic episodes by stress. It would make more sense that he gets manic when an album is coming out because getting it ready is when he undergoes the most stress.
That's a great point, I hadn't considered that angle. The only reason I would doubt it though is because I really don't think Kanye has been taking his meds at all for several years now. I think he's just cycling through mania once a year or so.
