There arn't any drugs that can completely eliminate suffering when you are starving to death, and as to whether or not she is even aware, why havn't we scanned her brain for activity, so we can find out, at least to some degree if she is aware or not? Doctors, reporters, and the general public alike, (including my self) seem to be just guessing at her condition based on superficial observation... But thats just because nobody is doing the real tests that need to be done in order to ascertain just how aware she really is. I dont think we know enough about her condition to just condemn her to starvation.
