Narrative:

I was on an IFR flight plan to spg. During the descent into the airport in the IMC condition; ATC clears me to fly direct to IAF (initial approach fix) jrgal. I was not sure if the approach that I load in the GPS was correct; so I looked over to verify. When I looked back at the instrument; since it was a descent turn; I got disoriented. It took me two to three seconds to recover; however; I ended up heading 90 degrees to the right of my course and around 300 feet lower. I then informed ATC and continue to destination without other problems.
