Marc,
congrats on two weeks,
seriously consider going to the doc for an exam. Smoking depresses many functions and hides many ailments, the shortness of breath could be something that needs treatment, but hey I'm not a doc, just MHO.
Anxiety could be related to pills and or patch, doc can give definitave answer on it.
Sleeplessness it one of the side effects of nicotine withdrawl, but it could be the result of the patch if you are wearing them 24/7 again IMHO
any way best of luck, RJ ...Free at Last 382 days after 32 yrs of two packs/day killing myself
