Is it an Allen Carr centre? I went to one in the 00s and it worked for me. The books are very popular too.

They said the biggest cause of relapse is becoming complacent because you’ve found it so easy to quit. This was the case for me - about six months later I thought I’d have a social cigarette because I was over it - and it wasn’t long before I was back to where I started.

But I did stop again and now treat smoking like former alcoholics treat alcohol - I won’t ever smoke again because it’s a slippery slope!
