oh p.s. when craving sweet things, some of my favourites (they are prob on the sticky already):
the "snack" or "fun" size cadbury bars - very helpful to buy the bag of these (in tesco) many are 1.5pts each (the mini kitkats, mini pkts of choc buttons etc..) and since they are the REAL thing (i.e. not low fat!!
) I often find they give me my fix 
a full size curly wurly is only 2.5pts, a crunchie 3.5 and a pkt of malteasers (my favourite cos lasts ages) 3.5
