Singapore Expats

Does Sigapore have any restrictions/rules I should be aware of around bringing common prescription drugs through customs? I am relocating and have some common prescriptions such as Ambien, in typical personal quantities. I assume they would need to be in the original bottle with presctiption info, is there anything else to consider?

I got my doctor to write a letter just in case i was stopped with my tablets. You should be fine.

No problem and only now have a letter fr the tablets when I travel to Australia.
