How to say "After +Verb" in Chinese? How to say "After +Verb" in daily conversation?

For example:

"After eating my candy, I will go there".

"After he saw you were coming, he left".

"After she found the book, she called me".

etc.

So the focus here is the "After" word. I know 后 is usually used for this case. But I wonder whether there are other alternatives?
'After' can be expressed with 以后 placed after the clause:

吃完糖果以后，我去那里。

The second sentence can be translated using an 'after', e.g.:

他看到你来以后，他离开了。But it would sound 'more natural' if you dropped it:

他看到你来，就离开了。
