When I tried to give up smoking (and I tried a lot over 20 years, 50 cigs a day) I just couldn't stop, because i was trying to switch from cigarettes to patches, or cigarettes to gum, or cigarettes to inhalators, or ecigs, or snuff (yes I even tried this), or hypnosis, or lozenges, or etc, etc, etc.
Nothing worked because i was trying to swap smoking for something else, and you can't help but compare the two, and the other thing just isn't the same.
So in the end a simple change in thought worked, and it sounds mad, but it worked.
Instead of thinking I'm going to switch cigarettes for patches, I thought I want to stop smoking, and I'm simply going to use patches to get over the cravings to keep smoking, rather than viewing it as an alternative to smoking.
So maybe, instead of thinking I'm going to switch life for death, I'm going to move from one to the other instead, if you really don't want to be here any more you think "Life is painful and I don't want to do it any more".
So I'm going to step off this bridge, and that's going to help me to overcome the cravings to keep going through this painful existence.
If you see what I mean.
