Yes it can happen at any time. Keep anti nausea meds on hand. I still get it once in a while, especially if I strain at all to go to the bathroom. I found that spitting out the excess saliva when it hits helps to stop the nausea. I think it's a protective mechanism to have excess saliva when your body senses nausea.
