What’s the worst reaction you ever have had consuming food, vaccine, medicine and or a drug?

7.5 mg of monjuro jab. Stomach cramp, dehydration, vomiting, heart palpitations, dizziness, diarrhoea like liquid that I had to sit on a towel for two weeks till it stopped leaking out. I went back down to 5.0 mg and back to normal again... but it was horrible
