I remember that a few years ago, after a few months during which I dabbled in street cocaine (which may not actually have been cocaine for all I know), I started to have occasional panic attacks. I then stopped doing that nasty stuff and would not do it again for many reasons, the danger of fentanyl being one of them, but I kept drinking alcohol regularly and continued to have occasional panic attacks. Even though I continued to drink alcohol, the panic attacks stopped happening when I started to take vitamin supplements daily: B1/thiamine, B complex, magnesium, calcium, niacin, and D. Most likely, panic attacks can also be caused by pure psychological factors, but I just want to leave this information here because it might help someone who is experiencing panic attacks. Of course, I am not a medical professional, so take this information for what it's worth, which might not be much.
