I'm Trying To Stop Smoking And I Was Recommended To

I'm trying to stop smoking and I was recommended to go on champix. Yesterday I didn't have any cigarettes only the tablets. I started feeling ill and started vomiting in the evening till I was bringing up bile. Today my stomach is feels swollen. I have been feel exhausted for a while even though I haven't done anything. Im also on the conceptive implant and I'm also wondering if the champix can stop it working?
