Hi Christine,
Just try to bring necessary things: clothes and personal medicine.
On medicine, don't bring in too many or you may get subjected to a thorough interrogation or have the medicines confiscated.
Although you may not find the items you've grown accustomed to, you may find alternatives here.
I think you can bring in 1 Liter of liquor and 1 or 2 reams of cigarette. But to be safe, narrow the cigarette to 1 ream.
Although I'm not saying you that you may have, please check your laptop for pornographic material. It's prohibited in here.
Regards,
Glen
