Thanks, Victor and congratulations. My Rog is taking chantix now and has been able to cut back a huge amount. He isn't quite there in being done totally with them, but I think that's more psychological and stress at work than anything else. He's just started his third month. He says it not only blocks the nicotine receptors, but seems to effect all pleasure receptors. He's noticed a glass of wine or a beer really have no "pleasure" to them now. I have been watching him carefully for any mood swings, but so far all I've noticed is a bit more grumpiness and that, again, could be attributable to his job more than anything. Regardless, he no longer wakes up hacking up a lung each morning and that is GOOD!
