How long does it take for bupropion to start working to help quit smoking?

I am am taken 150 twice a day for 12 weeks, tania starr

I am sorry I was trying to said 150 mg twice a day for 12 weeks

That's what I take, 150 in the morning, 150 at night. Well did, now I am taking 150 in the morning and plan on just quitting in a few days. I was on it for 14 months. So they have it setup that you take 300mg total daily for 12 weeks then that's it? No tapering? That kind of worries me, but I am not a doctor if that's the case anyways. But yes give it more time, I believe anywhere from 4-6 weeks is the norm before giving up. Good Luck to you as well, I never was a smoker but watched a few friends quit. One ended up doing it with gum and "SNUS". Just in case you can't find a med that helps.

thank you for your help god bless

I have been on it taking one pill a day. I started taking 2 a day two days ago. Last night I woke up feeling this strange feeling in my legs chest and arms. I couldn't go back to sleep. They are very mild now. I can't call my doctor cause I cant explain the feeling. Its not painful but very uncomfortable. I dont want to give up taking the pills cause I really need to quit. I'm 51 and need to quit for myself and my family. So, I have been on it for 12 days. I have a bad taste in my mouth and cigarettes make me sick but I still smoke a few. Really think this is going to help me but last night was pretty freaking. Any advise

@bridget24 - I'm with you - started 3 weeks ago taking 150mg 2X's a day, on day 3 had a case of 'mania' (that's the only closest side effect that could describe what I felt - can't call my dr cause her staff sucks) - been taking 1X a day now, 150mg in the morning (too paranoid to take more) - for 1-1/2 weeks now, a few days I've only smoked 1/2 pack and other days it's all I think of, some days the cigs are nasty and only take a puff or two. Going to be patient and give it a few more weeks per some comments here and other web sites. My cholesterol reminded me that I'm not young and time to give up some habits, eat better and exercise. 43 - had a good run but time to quit - but for some stupid reason I won't just throw them away! Good luck.

My Doctor gave me,Bupropion
75MG Tab APO,once Daily
To quit smoking. Others have
Higher mg,wondering if mine
Would do anything???

Good luck - I stopped taking it. Since my comment my cholesterol is down and have lost 30 lbs - but still smoking. It's on my list to accomplish this year. I have a friend that benefited from Well with no side effects. Good luck!

I have been on zyban for 8 weeks. I was recommended to take 1 tab for 3 days then 2 tabs there after. I completely spun out taking 2 tabs on day 4, having every single side affect possible. Being determined I decreased back to 1 tab, which I took for a period of 2 weeks until I thought my body had adjusted to the drug. I then took 2 tabs, it did spin my body out again but I was able to handle it and channel the drug and pushed through. I had my quit date early in week 2. It was easy as I felt sick even smelling a cigarette. I also have stopped drinking which was a trigger for my smoking and have lost 2kg.
8 weeks in still on 2 tabs feeling fabulous. I will remain on it for the next month then stop taking it. I am completely repulsed by the smell of cigarettes and it makes me feel sick. I am
Really happy with my progress considering I have smoked on and off for over 20 years. Zyban is not for every one tho
As side affects can be really full on and worse for some.
Good luck.
