Hello doctor, lately i'm experiencing some pretty scary cardiac arrest symptoms after eating too much sugar--chest pain, tingles down left arm, spasms?

Symptoms of cardiac: arrest are rapid heart beats, dizziness and loss of consciousness. Not what you are describing. Sounds like you are having a sugar high. Chest pain, tingles and spasms sounds like anxiety. For reassurance you should see a health care provider and have testing to exclude cardiac issues. Then you need to make better life style choices.
