Champix

I'm 32 years old, I have been smoking for about 8 years. I'm married, have two small children that I want to around for as they grow up because I love them so much. I can't bear the thought that this awful habit might rob me of that. I've been on Champix for about 10 days, smoked half as much as I would. Have no cravings, just the habit itself is hard to kick. First few days I was fuzzy in the head. For two days I've been on the stronger dosage. My sleep is terrible, and my body broke out in a rash, but now seems confined to my hands. I have hives on them and they feel like they are on fire. Hopefully the doc tomorrow gives me something for that because I can't stand the itchiness. Has anyone else had this?
