I'm on day 3 and finding things ok at the moment apart from the mouth ulcers are coming !! I tried packing in a few weeks ago and experienced these ulcers which was one of the reasons for starting smoking again. I'm going to try and ride it out this time and give it a couple of weeks to see if the ulcers get better without smoking. Has anyone else had problems with ulcers after a few days of not smoking ? I'm going cold turkey, not sure if this makes it worse. Any advice welcome.
