Soft food switch

so I am leaving on a business trip, so I wanted to make the transitionto soft foods a couple days early to make sure my stomach would tolerate it.  I have done fairly well, but my tummy is a little grumbly and experiencing slight nauseous feelings.  Is this normal?

Did your surgeon approve the early advancement of your diet?  If not, I hope you'll reconsider - the surgeon's plan exists for a reason.
