I could have eaten this and...

[Bobbert]

I could have eaten this and thrown the rest away
I could have eaten this and given the rest to you
I could have eaten this and gone to bed

After Podría haber comido esto........., do I use another verb “haber” to finish the second clause, or do I use an infinitive verb to finish the second clause?

Podría haber comido esto
1. y haber tirado lo demás, y haberte dado lo demás, y haberme acostado

or

2. y tirar lo demás, y darte lo demás, e irme a acostar

or some other construct that I'm not considering.

Any and all explanations and/or examples are greatly appreciated.
