Earlier quoted context omitted.
I was hooked on diet coke until one day I decided to take a break, and my tongue felt... weird. It felt slightly fizzy as if my brain was signaling that it was time to drink diet coke. On top of that, I felt lazy for a couple days. I'm glad I was that self aware because I stopped drinking it everyday. Maybe 1 or two a month.
>On top of that, I felt lazy for a couple days. probably because of the caffeine?
Not even the morning/noon tea would pick me up. It was a different kind of lethargy that’s hard to explain and it went along with this uncomfortable sensation on my tongue.
