No Buy= No Fun

Am currently on a no buy (will have been 4 months when it ends in April) , which I'm finding very difficult (hence all the FOTDs and reviews of products that have been out for a while). OCC lip tars are now available in the UK (and I like all of them), Too Faced and Urban Decay also have products I want to try out and there are a load of other things I want to try and it is becoming very hard to resist. I suspect that denial makes the compulsion to spend much, much worse and that I will end up spending a fortune when I allow myself to buy again. The worst part is that I am going abroad twice this summer (Sweden and Belgium- trips to the Makeup Store and MUFE are unavoidable) and since I am a full time student, pay my own tuition fees and haven't got a job I need to be careful.

Is it actually possible to stick to a no buy or does everyone break them?
