Really in a pickle...

Hey guys,stop smoking now,I decided to quit smoking a couple of days ago (chucked a whole packet of cigarettes, ashtrays, lighters etc. in the bin which was very hard), I'm doing OK so far I do get very strong urges now and then but when I can find something to occupy myself with they usually subside. However I believe this weekend coming will be a MAJOR test for me,Herbal cigarettes, I'm so used to smoking with my friends (Literally just about all of them smoke) that I can just picture myself giving into temptation and lighting one up , being 21 years old I have a lot of parties of good friends to attend this year and one of them is this Saturday night and I'm very very anxious, on top of that I have a close friends going away drinks at the local pub tommorow night!!!! It just seems like an impossible feat not to have a smoke Any tips on how I can handle these situations??? Anything I can do or think of when I feel that urge or if someone offers me a cigarette. I could just stay home this weekend but I don't need this addiction controlling my life I want to be rid of it!!!! I'd be so disappointed if I gave in... any help would be appreciated thanks guys.
