Dianne, I can't believe you started smoking again . . . I'm sorry. I know it must be hard seeing your husband that way. That would scare me to death.
Is he willing to try to quit? Have you tried the Wellbutrim? You will have to see a doctor. Wellbutrim was actually given to people for depression so it may help you out in more than one area. He really sounds like he needs to go to the doctor. I would make him an appt. and make him go. That's what I have to do with my husband. I hate going to the doctor's office more than he does, but it's not worth dying over . . .
Good luck to you both and keep us posted.
Lucky
