Welcome to diving doubles!
After a couple of dives you'll get used to it and eventually it becomes comfortable. I set up my single tank as high as when I dive doubles. It's better to be able to reach those valves than to be comfortable.
That doesn't sound smart. I am currently experiencing the same issue. If I really want to look straight ahead, I have to lean my upper body back, switching from horizontal positioning. And that is really annoying.
