Uhh just a heads up for anyone thinking of doing this, and is prescribed a controlled substance. I just found out Klonopin is prohibited from entry without a narcotics permit issued by the Korean FDA, even though doctors will prescribe you it if you bring your US script.
I found about this yesterday, the process takes 10 business days to get an answer on the permit.
I don't have time for that since I leave tomorrow morning, so I'm going to bring them anyway, because at this point I'm physically dependent on them and withdrawal will for sure make my tinnitus worse.
According to a few people I've spoken to, they don't bat an eye at pill bottles at customs (unless you are bringing in a metric f-ton).
I'm contacting a bunch of doctors in Korea frantically trying to make an appointment in case they don't let them in. The tinnitus clinic I'm going to will prescribe them, but I can't wait 3 days to get them.
Lovely!
