Phrase for giving up?

Question

I know there's a phrase that means giving up, but I can't remember it. It's in the context of the following question/text:

So you're saying I should just ________ and do whatever they want?

The phrase is similar to "pack it in", "swallow it up". It goes something like "drink it up" but that doesn't sound good.

Does anyone know what this phrase could be ?
