I don’t remember it as a treatment for it though but just for the mentioned symptoms, I could be wrong though.

This I heard watching a documentary on the subject. Watch the dosage though if you're a non-smoker. I tried a 4 mg lozenge a few days ago and thought I was going to die from a heart attack, so my advice is to start as low dose as possible then increase gradually to tolerance.
