answer:I have never quit. In fact, I kind of want to quit, but I’ve been in a terrible emotional place for a while now, and I have read that quitting smoking can trigger or exacerbate depression, especially in people who have a history. Nicotine is considered to be a mood altering substance, and quitting can have a very real effect on your emotions. Definitely talk to your doctor about it, it is likely that there is a link. He may be able to adjust your medication, or find an alternative that would be beneficial to you. Hope that you feel more like yourself, asap.
