Thank you. It's a good solution. With Semiclassical's substitution it works well.

comment Solving weak 2 body problem
Another point is I can try to solve the final differential equation by direct integration. But it seems ugly and I'm looking for a nicer way.

comment Solving weak 2 body problem
Thank you very much for checking the calculations! The most problematic thing here is manipulating higher order derivatives and for this reason I couldn't understand that $dx$ is wrong, $dt$ is correct. Sorry doing mess writing the solution, now I fix it.

This idea works. As hjpotter92 wrote I get an easy form to integrate.

Try this: en.wikipedia.org/wiki/Lambert_W_function#Example_1, maybe what you are looking for.
