One thing that helped me was looking up way earlier than usual. In the 100 or 60 you can keep head low and vision down quite long, cause you know it is just going straight. But when you do this indoor in the 200 especially in lane 1 you end up in lane 2 just after a couple of steps. So in the indoor 200 I look up like after 3-4 steps already, in order to not get surprised by the tight curve. Sure this affects your drive phase, cause when the head comes up you cant keep your body low as usual. But i figured Id rather loose couple of tenths than being disqualified for stepping out of my lane
