I could probably go without the Miralax...I've actually considered that just recently too!! I don't know why I haven't increased my Acacia and decreased my Miralax, I guess probably just b/c it has been working!! I have to get a prescription from my doctor for that, and I don't really need any other refills, so I've considered just not using it.
Its hard to say what type of BM's I have....but, at this point, I am happy when I get anything out - a little or a lot! (Sorry, I know thats probably gross. )
