After a few severe scary bouts with constipation, here's what has totally resolved my problem: Yakult probiotic (2.7 oz bottle/day), sesame oil (drizzle on soups, etc.), coconut milk (canned whole-fat type on cereal), magnesium (1 pill/day), and avoid pasta & cheese. Works for me, and what a relief! Some might say this is too much, but I don't ever want to go through that again. Of course, I also exercise, eat high-fiber food, and drink lots of water, but it just wasn't enough. I've seen others on this forum mention this issue, so perhaps it's worth a try.
