Look at the data usage graph, work out which apps are consuming the most data, and if you need them running then configure them to use less i.e. poll less often for updates, sync at longer intervals etc. If you don't need them then either disable them or log-out of the associated accounts.
Check that "Show wifi usage" isn't enabled in the Data Usage
menu, as this will artificially skew the figures.
