smoked a pack a day for 10 years. In March decided to switch to Vuse...in July decided to just chew Nicorette...had what I think was a pretty severe allergic reaction to Nicorette. Felt awful, heart palps, severed edema, a visit to the ER with a chest X-ray and eEG showed perfect health. Had Lyme tests and blood work multiple times...all clear. 8 days ago, decided to stop chewing the gum so basically went cold turkey. I have never felt so crappy before. My legs hurt, my entire body is swollen (scale up 10lbs since I started chewing a month ago), head in a fog, crazy bloody nose yesterday. It's really been awful. Are these all common withdrawal symptoms? I have been giving myself semi panic attacked because I keep thinking something is genuinely wrong..although the doctors have not found anything. Please help if you've had any of these symptoms. The only good thing is I have absolutely ZERO craving for a cigarette.
