No clue what any of that except the MD thing, and haven't been there in at least 20 years. I literally will not touch the energy drinks. Shit makes my heart race. I'm probably 15 years older than you, at least.
Hi-Chews are basically like taffy but they don't stick to your teeth I've found so I don't have to worry about losing a filling lol. Think they have been around for a really long time but they are a Japanese candy. Energy drinks don't have much of an impact on my heart or anything else that I notice. I just like drinking them for the bite in the morning.
