For Smoking Cessation "I'm taking Zyban SR 150 mg twice a day. I started with once a day for 7 days on May 10, 2017. So I've been on it for 12 days. I have stopped smoking, which is the goal, for 3 days. Should I stop taking this medication soon? The side effects are overwhelming. I am flushed, have chest pain, a bad taste in my mouth, sweating, nausea, my head feels foggy, my ears have pain with a fullness feeling, I am constipated, and more. Will the side effects go away?"

For Smoking Cessation "I found Zyban to be very effective and easy to use. I only experienced a few mild side effects (slight constipation, food tasted a bit different). But I'd tried quitting before using gum, microtabs, patches - and none of these worked for me. Thanks to Zyban, it's been over four months since I smoked a cigarette and haven't turned back - proud to be a non-smoker!"

"I have suffered with anxiety for many years, which sometimes leads to depression. Zyban was prescribed for it. For the first 2 days, I was wired, my mood was focused and neutral. I was not bothered to eat at all and just kept doing chores all day. I was wide awake at night. Day 3, I noticed I was constipated and ended up getting a mild laxative to help me go. On day 3, my anxiety came back, although about 2-3 times as bad as before. Instead of being me with anxiety, I felt like a shell with anxiety. I could hardly keep tears at bay at work. I simultaneously cared too much and not at all about everything. Everything seemed gray. I looked forward to nothing. Felt no joy and couldn't smile. Constant adrenaline and fear. It was like a living nightmare. I had the odd moment of relief here and there where I could function, but still felt like a walking shell. Now, after 2.5 weeks, I can't take it anymore. I don't usually quit things, but it's too much. I'm quitting cold turkey and starting on Ciprotan tomorrow."
