It wasn't very nice for your doctor, or maybe it was the nurses, to let you have nausea to the point of dry heaves all night. There are plenty of meds to stop that. In fact most of us wrappies carry some around with us all the time - just in case.
My doctor, who is a well-known expert, says absolutely only clear liquids for the first few days, then "full" liquids (add milk) for a couple of weeks, adding soft foods slowly.
I agree with Denise. If you have a full wrap and can't burp easily it is no good to even dream of drinking sodas. You will be in excruciating pain if you can't get the gas up. If you want to heat the soda or let it sit uncovered for at least a day you might be able to let the CO2 flat, but then it tastes like corn syrup and water, which it is anyway.
