How I quit in one week
I was addicted to zyns/cigs for 3 years and was going thru a pack of the extra strong ones in one day. (Probably crazy amounts) I decided to quit cold turkey because other attempts of gradually lowering the dose failed.
I bought a ton of mouthwash and the mintiest most gross gummies and mint candy I could find. I couldn't go a minute without having zyn taste in my mouth so I figured that would be a good substitute. I just constantly drank Alkohol free mouthwash and ate mints until I no longer felt miserable it took about a week but well worth it.
Other foods I found to be a great substitute were:
Liquorice
Mate (German drink that tastes like cigarette buds)
Kvas (russian root beer)
Brause-Pulver ( German candy thats sour and tingels on your tongue similar to zyn)
Lemon juice + highly carbonated water
Gross energy drinks (the cheap kind like booster or king Kong)
Good luck !
