a) try to find a way to fill declaration of prescribed medications for customs and for police. (let the google/llm and local adhd communities help you) Find verified cases of how that have worked for others in your particular country.
Sometimes workarounds exists, but it would take some paperwork
b) plan a trip to the Turkey, find a specialist there, get the prescription, do all the paperwork/preparations before going back
c) fill all the papers and get the approval at customs even if they didn't know about that before - prepare all the necessary links to official documents, as maybe you would have to explain them how to do their job
p.s. I know that feeling. Atomoxetine is full of side effects without direct effects.
