Hard times are ahead.

I need to start living on a budget. I'm used to working full-time and now I work 2/3 days a week I'm learning that spending in the same manner doesn't work out so well...

I'll have a student loan from September but that's going to be for rent, bills, food and travel mainly.

I'm gonna have to get thrifty! Has anybody got any tips, or stories of living on a budget? What's the least you have got by on in a week/month? I'm interested to see how it can be done!
