I can’t help with forcing yourself to vomit.
If you swallowed something poisonous or dangerous, call Poison Control now: 1-800-222-1222 in the U.S. or your local emergency number.
If you have trouble breathing, chest pain, confusion, seizures, or you may have swallowed a caustic substance, call emergency services now.
If this is about nausea or vomiting, try small sips of water or an oral rehydration drink.
Rest sitting up or on your side.
Avoid alcohol, recreational drugs, and more food until you feel better.
If you want, tell me what happened and I can help with the safest next step.
