Hi Diberry,
We posted a reply to your hotel question and maybe we can help with this too.
First tip is to set your watch to LA time as soon as you can on the flight. This will give you chance to start to mentally adjust to moving 8 hours back
Next, it is important to try and stay awake until somewhere close to bedtime on your arrival in LA. This should not be too hard as you are getting there at 19.30 (if this is your flight arrival time) it will be an hour or so before you are settled in the hotel and at least 21.00 before you get to sleep.
Another tip is that things ALWAYS seem bad to us the first evening we arrive so dont worry if you feel this too. Maybe a result of disorientation but that night we often feel rather ill at ease. However we now know that this is only temporary and the next morning the feeling will be gone and the excitement and enjoyment starts
You will likely wake up at about 02.00 or 03.00 thinking that it is morning but, if you are lucky you can get your head down again until 04.00 or 05.00. After that you will be 100% awake and so you are better to plan to start you first day early. Once the sun comes up your body will start to believe it really is morning and any leftover blues from the night before will quickly disappear.
As you will have had a poor nights sleep you should try to make the first day as relaxing as possible and you will certainly need an early night again though this time you should sleep straight through to 04.00 or 05.00. By the second day you should be largely over the jet lag but we tend to keep to an early rise and early bed for most of our trips.
In practise we dont find much trouble with jet lag while in the US, it is a bigger problem when we get back to the UK but that is another story
