I have no direct experience of patches -I went cold turkey when I quit smoking, nearly 3 years ago now - but I did eat a snack or some crisps when i got the craving, resulting in weight gain. Better lungs, but tight waistbands - not sure it was the best trade off :)
I have not heard of those particular symptoms you describe as common side effects of nicorette patches - rashes, redness, itching etc are reported more frequently. Might it just be a pyschosomatic effect of nicotine withdrawal?
I have also included a link to a good article about someones battle with quitting smoking in todays Independent, if you are interested :)
