You could try a Nicotine inhalator - really helps me in such situations..

People there are saying they can be expensive, which I've not noticed as they are on prescription for me over here. (and a free prescription might I add.. insane!) oh and they are also saying that it looks like a Tampon .. This had not occured to me!!
But, if you're keen to stop - these really help.. you just have to weigh up if you want to still be consuming Nicotine..
Anyway, big ups mate!!! Your doing well!
Cheers,
