Again anecdotal, but I've had a similar experience. I've been trying to reduce the amount of refined sugars in my diet, with the aim of being completely off refined sugars/artificial sweeteners at some point this year. I've been eating mostly just fruit for dessert after dinner. It's really good because after dinner is one of my sweet tooth triggers. Well I got the dumb idea to eat a piece of a chocolate turtle candy instead and within 5 minutes was sweating and my heart was racing. I had the lightheadedness too. I felt awful. On the plus side like you said this kind of experience helps me not want to eat it more. I started an open facebook group with a few friends so we support each other in not eating it. It's been super helpful too to have someone help keep you accountable.

Lustig, MD, UCSF Professor of Pediatrics in the Division of Endocrinology titled "The Bitter Truth". https://www.youtube.com/watch?v=dBnniua6-oM&t=1s https://www.youtube.com/watch?v=dBnniua6-oM&t=1s This, in addition to a lot of reading about world history of sugar trade and how disease is usually right behind the introduction of sugar is a large part of my personal decision to try to stop eating it.
