Vomiting in The Sims 4 is a symptom of specific negative states. Here are the triggers and fixes.
| Cause | Trigger | Prevention |
|---|---|---|
| Food Poisoning | Eating spoiled (red freshness bar) or poorly prepared food (low Cooking skill, dirty stove). | Refrigerate leftovers; upgrade stove; hire a cook; check freshness before eating. |
| Morning Sickness | Pregnancy (1st trimester). | Unavoidable; "Try for Baby" chance. Eat crackers (debug) or wait it out. |
| Illness | Virus, Bloaty Head, Gas & Giggles (Get to Work). | Medicine from computer/phone; rest; doctor visit. |
| Extreme Emotions | Hysterical (Playful +3), Mortified (Embarrassed +3), Enraged (Angry +3). | Manage needs; use "Calm Down" mirror interaction; avoid stacked moodlets. |
| Alcohol (Mods) | WickedWhims, Basemental Drugs, or custom content adding drunkenness. | Disable mod or moderate consumption. |
| Cheats | sims.add_buff buff_Sick_Vomit or similar debug cheats. | Don't enter vomit cheats. |
Shift-click Sim → "Cheat Need" → "Make Happy" (requires testingcheats true) instantly clears negative moodlets including nausea.
