It’s kind of silly how you have the control of a blackout drunk sorority girl when it comes to not throwing up all over the place. You should get a warning along the lines of “You feel like you are about to throw up” which can give you some time to go outside so you aren’t throwing up inside your base.
What difference does it make where you throw up? The bile is completely cosmetic and can be cleaned up using a mop, otherwise it goes away by itself after a day. If you’re at a point where you’re going to throw up and there is nothing you can do to stop it, you’re going to suffer the negative effects of throwing up one way or another; it’s not like you need to remove headgear or do anything special so the effects don’t get more severe.
