Tinnitus and quitting 15mg zyns

Quit cold turkey about 17 days ago.
Used about 8-10 15mg pouches a day for the last couple of years.
Have also cut caffeine intake around 80 percent.
I’ve had tinnitus for an about two years but it comes and goes in severity.

Since quitting I’ve had a bad spike. Morning to night. A little easier to manage in the morning.

Anyone suffer from tinnitus and found that quitting nicotine helped?
Been having insane anxiety, panic attacks, racing thoughts, tight chest.
I feel like my dopamine, neuro system has been in overdrive for the last 5-7 years because of vaping, smoking, zyns, and caffeine.

Doing everything I can to push through.
I’ve also been sleeping less than normal?

I need some encouragement, anyone else having a hard time?

I hope all you guys are fairing well on the quitting journey.
