NO NO NO!!
Ride in the direction you are going!!! Always. Please! Riding going opposite traffic is unsafe on so many levels: Cars expect bikes to go with traffic, you can disrupt bikes going in the correct direction and pose a danger to any cyclists who are doing what they should be doing.
I can't even imagine switching lanes mid curve

That requires you to cross the road - with cars possibly coming up behind you.
Please ride on the RIGHT side of the road (assuming you aren't in the UK) - as far to the right as it is safe to be.
Sidewalks are not meant for bikes, but it's a heck of a lot safer than riding on the wrong side of the road.
