Is survival possible after having gravity reversed on the entire human race?

In the near future, an alien race finds Earth, learns how it and everything on it works, and begins to tamper with it. Somehow they figure out a way to flip the pull of Earth's gravity on only humans so we fall into space instead of falling to the ground.

They do this instantaneously to the entire human race and a theoretical half of the entire population is pushed into space and dies immediately (one half is sleeping inside, the other half is awake outside). Those who survive are now standing on whatever was above them and mad because they didn't get enough sleep. The survivors must figure out new means of transportation and general living techniques among many other things. Also, a vast majority of existing structures will be rendered useless.

Assuming the human race doesn't just decide to burrow into the ground and set up camp there, would we be able to adjust to this change in time to be able to survive? If so, how?

Notes:

1. Gravity's properties still work the same way. For example, you step out from under a platform and you fall upwards, accelerating at 9.8 m/s^2 until you reach terminal velocity and run out of oxygen.
2. Since only humans are put through this, all other living things stay the same. This means your cat is now on the ceiling (relative to you).
