No, you are not to tall.
I am 197cm and I have never run into a problem because of my length at both FAA and JAA medical examinations.
I am currently flying B737's and there is PLENTY of room to spare. You can adjust the seat in so many ways that it is really no problem.
The only time you may have some problems due to your size is during initial training when you have to fly small single engine aircrafts. This is something you have to think about when choosing school. When I started flying I was also concerned like you so I asked the schools I was visiting if I could test sitting in their aircraft.
Until now I have flown around 12 different types of aircrafts and the best for tall people are the C-172 and PA-28.
When you move up to commercial (western) aircrafts you will not encounter any problems. Maybe in some business jets, like Lear jet you might have problems.
Stop worrying and good luck with your medical
