Yes, Yes it does.
I found the XR works better for me, too, but it's mainly because I'm bad about remembering to take pills. Once a day makes me much happier!
man, my dh would kill for one dose a day-i can't understand why when the max (and not that uncommon) dosage is 225 mgs the pharmaceutical company can't make one in that strength (it would save me from having to get two strengths with 2 separate co-pays every month!).
