Boredom isn't your problem Kza, addiction is.
I don't know anyone who has quit who hasn't had to put a lot of effort into it. That can cover your boredom for now. Either start reading literature on addiction, or get yourself to an addiction agency who can help you and commit to going. We all have to do things we don't want to do sometimes. Living in the UK you have a load of free services that are available for you to use. It seems daft sitting there saying you don't want to go to AA when there are plenty of alternatives on your doorstep.
Don't you think you have tried this on your own for long enough now?
