Do not use a common neutral. Each outlet needs is own common return.
If you use a 20A duplex break and 12 gauge 3 wire (4th wire bare ground)
romex (rated 20A IIRC) and install 20A outlets, the two hot leads will
be protected to 20A but a common return could be carrying 40A if you
plug in 2 20A loads, twice the rating for 12 gauge.
