I know it's a month after you posted, but I just saw your message and I thought you might like some more encouragement.  I also felt like I never stopped nursing at the beginning (plus one had a tongue tie which meant he nursed painfully for 45 minutes - 1 1/2 hours and I would still have to supplement).  But now they are still nursing 2x a day at 18 months and I couldn't be happier that we did it.  One thing that kept me going was the euphoria (I think it's chemical) that came over me in spite of the pain whenever they nursed.  I could be in a state of panic and self-pity, and as soon as they latched on I felt waves of love sweep over me.  I look back and I miss the long stretches of time that I had nursing with them.  So quickly they become very efficient and nursing can take 5 - 10 minutes.
