Have you had a lesson since your adjustment? It sounds like you need to get used to the new set up of your clubs.

I am assuming you are on the shorter end of the measuring tape to have your irons bent 2* flat. What you will need to do to adjust to the new set up is move the ball further away from you when you hit. This will also cause your swing to be a bit more shallow. By adjusting your clubs 2* flat, the club head now must be further away from you to keep the sole flat on the ground. This will take some getting used to, but with proper practice the adjustment will pay dividends in the end.
