They don't make you trip. If that is what you were expecting you really should have done some better research before swallowing a pill. They give you typical opiate effects and that's about it: warm fuzziness, heavy head, itching, nausea, etc... Although what others have said about allergic reactions is great advice. Opiates don't make me puke personally although for some people it is inevitable, but nothing to worry about. Be safe please!
