Lemonade Slush Burns Mouths - Sonic, Alamo Tennessee

1340 West Church Street, Alamo, 38001 Tennessee, United States

Lemonade slushes from there Three people in my family got mini lemonade slushes.  Immediately they all started saying they didn’t taste right.  I tried one and it burned my mouth.  I swallowed part of it and spat the other part out after the chemical and acidic taste hit me.  20 minutes later everyone that got the slushes (plus me so 4 people) began throwing up.  It burned my mouth and gave us diarrhea.
