Miralax gives me incontinence, no matter how much I decrease it. Just doesn't work for me. And, it takes 2-3 days for anything to work. It's never the next day. I learned that this is to be expected, so I don't worry if nothing happens the morning after a pill or two. I have found that Triphala, an herbal big pill helps me alot. Got it on Amazon.
Cannot tell you ingredients, but it works for me. 1000mg in each pill. Enough to get things moving.
