Hello, Doctor. So, I have been lounging on my bed, watching a series on my laptop and drinking soda when suddenly my heart started beating really fast and it kind of felt like that experience of a panic attack but it wasn't one 100% as I've experienced those in the past and nothing triggering was there nor was I scared. I haven't eaten too healthily last week though, mostly cereal, pizza, chips and soda. Could it be something to do with that?
