What to take with me for Tomorrow-4 days

Going off to London tomorrow for 4 days to visit family- Just wondering what types of things I can take from here so that I don't get the urge to pick there. We are staying with my husband's family who normally have all Asian curries, briyanis, kebabs, samosas, naan....God Help Me!
Any ideas welcome

Mughshots, Alpen lights and loads of fruit. Keep drinking water before meals as you feel fuller before eating.

Have a great time and don't worry too much.
