Go pasta. got me through most of my first term that little beauty. The only thing I can recommend for fresher's flu is Vit. C and lots of it. I didn't take it and caught the flu, was really rough for the next month or so. For xmas month (always great time for partying), I took it and was fine.
that butchers is quality, best bacon and eggs ever. Go to the markets for fruit, veg and meat as they're normally cheaper and fresher. Supermarkets are good for all the other stuff, like pasta, beans, drink etc.
