Allegra works well for me, and I now use the one-per-day (180mg) dosage. If the allergies are really strong I boost the Allegra by taking a Benedryl at bedtime. I can't take the full dose of two capsules or I wake up hung-over (benedryl just does that to me, it isn't the combination). My son does fine with Allegra-D, and one in the morning is enough to last him for 24 hours (Though you can take one every 12 hours).

Take a shower at bedtime and wash all of the day's accumulation of pollen out of your hair. And/or you might want to change your pillow case each evening. That way you don't have your face right against the fabric that is carrying the pollen off of your hair while you try to sleep.
