I can give another recommendation; while you may feel the effects in your neck, it can start well further down from your feet up. Do calf/thigh stretches, tilt your hips "back" (tense your buttocks, do kettlebell swings, dead lifts, squats), shoulder exercises (rows), etc. You can often tell when people have a desk posture from their hips being tilted backwards and/or pot bellies (even if they're not overweight).
