Mr. C/Cooper questions (Part 3 of The Return)

Hi, a couple of questions regarding Mr. C and Cooper after watching Part 3 of The Return:

1. What is the significance of the puke during the "getting pulled back to The Lodge" sequence?

If you rewatch this section, the way it is shot seems to be strongly implying that whomever holds on to their garmonbozia puke the longest wins.

They go to great lengths showing Mr. C desperately trying not to throw up and you see the red curtains start to appear (he knows what's coming) and then you see Dougie throw up (after making NO attempt to hold on to his puke) and then Dougie gets snatched by the Lodge instead and then FINALLY Mr. C releases his toxic barf all over his Lincoln...and he's safe (from the Lodge anyway).

Any theories on this?

2. If there had not been a Dougie tulpa and Mr. C just sort of went along with the rules of engagement and accepted his fate to return to the Lodge, would Cooper still have gone through the same sort of "Dougiesque" mental adjustment period if he had been squeezed through Mr. C's cigarette charger instead of Dougie's power outlet? Was that recovery always going to be necessary no matter who Cooper was "replacing" in the real world?
