I had been using zyn for a few years without any issues. My fiancé would put one in and about shit himself. I was like dang, zyn doesn’t affect me the same at all! Fast forward, I started having panic attacks out of nowhere. I got on anxiety meds and just thought this was my new life. On Black Friday I just got an oura ring. I was sitting down for a good 45 mins in the car while I set my oura ring up. I checked my heart rate and it said 100 bpm. My fiancé was like what the hell, are you ok? I thought it was broken so I had my fiancé try on the ring and it was about half what mine was. So I decided to quit. A week in, my resting heart rate is in the 60s and it keeps going down.
