I would be interested in knowing more about this, since this may hold the key to you getting better sleep. Otherwise I'd be looking at getting up early, restful behaviour onboard, promotion of REM sleep (so not booze), light exercise and access to light at the right time. Difficult to be more specific without details of where you are starting and going! But sleep has a fairly systematic logic to it, so it should be possible to draw up a programme of behaviour and activities that will greatly help you feel either well rested or at least get you back on track quickly. It's possible to ger rid of jetlag altogether if you press the right buttons.

I would strongly resist suggesting sleeping pills for a one off event. Different products do vary in impact but they are not a first resort to my mind and some are unduly impactful in this context.
