When you are knitting back and forth, first you work the right side and then you work the wrong side. The only reasons for putting an afghan on circs in this case would be because of the length.
Do you find that you are working the right-side stitches on the wrong side rows? Just keep track by remembering that the odd number rows are always on the same side (usually 'front or right side) and the even number rows are always on the wrong side (usually 'back or wrong side).
Either a stitch counter or just paper and pencil can help you keep track.
