I worked as a research scuentist in the pharma industry for many years, including the company that invented Wellbutrin and I can tell you that it is not a drug to be taken "as needed." You need consistent blood levels for it to be effective. If you are getting any benefit from taking it irregularly, it's placebo effect.

You seem intent on simply finding the most easily manipulated physician out there, even if it's not to your own benefit. Good luck with that. I hope it works out for you, I really do.
