Indeed there seems to be a conflict between MWI of QM and the feeling of
consciousness.  QM  evolves unitarily to preserve total probability, which
implies that the splitting into different quasi-classical subspaces reduces the
measure of each subspace.  But there's no perceptible diminishment of
consciousness.  I think this is consistent with the idea that consciousness is
a
computation, since in that case the computation either exists or it doesn't.
Two copies don't increase the measure of a computation and reducing it's vector
in Hilbert space doesn't diminish it.
