Meeeeeeeeeh I have. I have a serious illness + migraines and when that happens I generally am puking every 20-25 mins and I have no energy to run to the bathroom every time. Plus I get super hot when it happens and the fan helps me from passing out. Granted, it's not full on vomit it's mostly gagging with some spit, and I have official hospital puke containers. I also don't make anyone clean up after me.
