they do give a damn they however cannot legally give out more than 3 months of prescriptions though as the system will not allow it, also last I checked doctors don't make laws and legislation, so why you are blaming them is beyond me 🤦
Not going to get through customs, even with tea money. If someone I know couldn't get a couple of inhalers through, or a different person I know couldn't get 1 month of blood thinners through customs it's extremely unlikely you are going to get 3 months worth of pill through.
Try Medisafe, it will probably still be "expensive" but around half the price of what you're being quoted in my experience.
I have taken many short trips around Thailand over the last few years and never had an issue regarding TM.30 when doing 90 days or the extension. (BKK)
That being said though, as with everything in Thailand, your mileage may vary
Had a message from a friend earlier who is going home after just shy of 7 months (1 TR + Extension and 2 visa exemptions + 2 extensions). Apparently when the original IO scanned his passport they took him to a supervisor, the supervisor just scanned the passport again, stamped it and sent him on his way. When he asked what was wrong the supervisor just smiled and said sabay sabay (Left via DMK)
Sounds like this could be the most logical reason as to why
It will be announced like every other time a note/coin that has been removed from circulation. They will slowly remove old notes until there is only so many in circulation and then announce that you have until X date to exchange/use the old note/coin.
