So basically you ignored the packaging, didn't read up about the drug and you are moaning because it went poorly.
Google.com is an amazing tool bud, even more amazing is the instruction manual put in the box to ensure someone without google.com knowledge reads it. I googled this for you:

Perhaps try it first then come back and tell us how it has gone. You basically put your body into shock and withdrawal and then proceeded to take champix while your body was fighting hard for it's craving. The only thing that i can see that has failed is the user of champix, the drug has not been utilized properly thus the outcome is determined by ignorance.
Now smoke as much as you did for the next month and give champix the proper chance to help you. Honestly i cannot believe you would take champix without following the guidelines.
I have quote a section that may be of use to you as i fear you may not click the link provided by google.com:
Before starting your course of Champix you should decide on a date in the second week of treatment (between day 8 and day 14) when you will stop smoking. You should write this date on the pack as a reminder. You will need to keep talking the full 12-week course of Champix tablets even though you stop smoking in the second week.
Now when you have followed this procedure and the outcome is the same then you may have some credibility. Another issue i fear may defeat you, you seem like you want to stop but i get the sense you are looking for any sort of opportunity to convince yourself it is easier to smoke. You need to realize you are about to go to war. Your mind vs your body. If your mind in on the same side as your body the war is over.
Just in case you miss everything i said try this quote and see maybe it makes sense:
Tell your physician or pharmacist if you notice any of the following and they worry you:
Headache, difficulty sleeping sleepiness, abnormal dreams, dizziness, feeling weak.
Constipation, feeling bloated, indigestion, flatulence, dry mouth
Nausea (feeling sick), vomiting stomach discomfort
Increased appetite, changes in taste
The above list includes the more common side effects which may be caused by your medicine. They are usually mild and short-lived.
So let sum up your champix experience, you never followed the guide, you never knew the symptoms in the initial days while your body gets used to the drugs and you came on here and told us how kuk champix is. In general anti depressant type drugs like champix, zyban etc will for the first week make your feel a bit sick as your body settles into them, suck it up and fight the war with your mind.
I would suggest your quit date on a friday, gives you two days to get used to the drugs and perhaps you can book the monday off just in case. How about you try it properly so you can give the rest of a much better review. I am planning on taking it 1st of may, at least i know i will be prepared because unprepared people end up like you
Did you even take the correct tablets in the correct sequence or did you slap any colour back?
