"Hi guys. I'm thinking about using Champix to help me stop smoking. When I spoke to my GP about possible side effects he really played them down. After having read some of your experiences I'm really not sure I could handle some of the side effects you mention. The nauseousness for example. I'm hopeless with nausea!! Is it really debilitating?? What other possible side effects should I be wary of? Any advice you could give me would be gratefully received. Thanks in advance."
