Its interesting to read that others at the same point as me are having difficulties. I am having an internal battle with myself most days. I will be honest and admit to having had some sneaky drags on cigarettes, yesterday was one of them days. I feel crap, headaches most days, think they are tension headaches in the temples. i do use a nicotine free vaporizer which helps, but probably doesnt help with the triggers in the brain which i respond to with the vaporiser. I waste too many hours having an internal debate with myself between "just have a fag" and "but its killing my lungs", arggghhh so fed up!
