I'll put myself in the "you cease to exist" crowd. There's certainly some question of what you experience as the body shuts down, but I see strong reason to believe that our minds are entirely the product of our brains, and so once the brain shuts down, that's the end of the mind.
Depressing? WEll, I didn't feel bad before I existed, so I doubt I'll feel bad about it after. In the meantime, I find life far more interesting than death.
It's not like we haven't heard all this many times before, you know. But if your god has a different idea about the afterlife, send him over to my apartment, and he can tell me about it.
