Ibogaine may be useful for you. In fact, its well known ability to help with chemical dependency seems to be a result of a mechanism which resets habits in a general way. So in the case of addiction, the brain returns to a pre-addictive state, but this also appears to work on other habits, negative thought patterns, etc. In addition, the spiritual component gives the user a new perspective on their thoughts and actions, helping to identify the causes of problems. Finally, there seems to be a several week long afterglow, an anti-depressant effect, possibly produced by levels of nor-ibogaine still in the system, which provides a window of opportunity and the motivation to make changes to your life.
Having said all that, an ibogaine experience is unlikely to be enjoyable, you definitely need a sitter, as it will probably make you nauseous and uncoordinated (ie unable to get to the bathroom unassisted). And it can be dangerous for people with a pre-existing heart or liver condition, so ideally you would get those basic functions checked first. Obviously you should not take any other substance before or during the experience. Afterwards you probably won't want to.
Iboga in its traditional setting is considered a medicine, and not just for mental issues. The current usage for chemical dependency probably just scratches the surface of what this remarkable plant can do.
Although the experience is generally harrowing, I believe 'bad trips' in the traditional LSD/mushroom sense are less likely, and the chances of being traumatized following the experience are very low. But it should probably be avoided by those who are bipolar or have a specific disorder such as schizophrenia, just because not enough is known yet, so it's too risky to predict the outcome.
It terms of other options, I have found that very low dose psychedelics, particularly mushrooms, have a very pronounced mood-lift and afterglow, but that's more of a short term thing. Ketamine might also be effective in the right environment, but it has other dangers so is not ideal. As thisusername pointed out MDMA can completely fix those symptoms. This temporary relief could be useful in a therapeutic context (ie exploring issues with a therapist), but unlikely to provide lasting benefits if taken in an unstructured setting. (And possible physical risks from extended use of MDMA count against it.)
