From what I read the main ones they watch for are Tramadol, Diazepam (I'm sure I'm miss spelling these lol) and one other I forgot which and, as noted above, another is Sudafed with whatever is in the behind counter version. I am going to travel with all mine in the bottles and the one I feel unsure about I will carry a letter from my doctor why I take it and hope for the best.
I feel like Athens is a huge place with many people traveling to and from other places and there has to be people with multiple meds needed. So I'm going to go forward as I normally do and hope for the best. We go at the end of July. I'll update this thread with what happens.
