Disrupted Sleep

Normally I dont get affected much by jet lag. Over the years of extensive longhaul travel I have learnt to regulate my sleep to minimise the effects (some might say I had plenty of practice with the boozy life of a student).

However, the last few nights I have struggled to settle in to a normal sleep after several short trips to North America, Asia, Europe and Australasia over the last few weeks. So far the usual tricks haven't worked so I'm looking for something to break me back into my normal cycle.
