It's bupropion SR, I'm on 300 mg and 150 mg Lamictal. If you haven't done well on other snri's you probably want to ask for a different class of drug. Zyban and Wellbutrin are both used to quit smoking, but that's secondary to being anti-depressants. I'm surprised Zyban is only prescribed to quit smoking. Odd, really. And you're on sertraline, which is an SSRI but can't get prescribed Prozac or Zoloft? Maybe that's due to costs? I didn't do well on Prozac (hence the Wellbutrin), but my sister is exactly the opposite. My other sister is on Seroquel (she's BP I) and my brother is on Lexapro. All of us are on generic Lamictal. I guess we're a pharmacoepia family
