I'm desperate to quit. 30 plus years and start of emphysema is enough. Only problem is I've tried everything else and this is my last hope. I'm still smoking. Maybe a little less but I'm on day 7 and I am always feeling off balance and in a fog. If this don't work I don't know what I'm gonna do . Taking half at bedtime and whole in am. Which is an increase from two halves a day after day 3. I am so desperate to quit. Anyone else have this problem?
