my wife, son and friends will be travelling to bali in oct ( my 14th and her 6th time). my wife has a serious back injury and takes a concoction of medication including ms contin (powered morphine) ordine ( liquid morphine) oxycontin, valium, panadiene forte just to name a few.i have read with interest lately about people afraid to take their prescription drugs with them to bali and end up leaving them at home .my belief is if you can do without them in bali then you obviously do not require them in the first place.with my wifes drugs we obtain a letter from our gp stating which drugs she is taken, we declare we have narcotics on our declaration forms we present them to customs with the letter and we have never had an issue. so do not panic if you require medication while you are in bali follow the correct procedures and you will be fine.
