Sorry, just saw the question! I think ipsaghula husk is the same as psyllium husk that some people don't like, but I found after a week or so it suited me fine. There's orange or lemon sachets, and I find the lemon quite nice, a bit like homemade lemonade. I get it on prescription (a lot cheaper!!!) but it is generally available over the counter at pharmacies so might be available in the US - perhaps Heather would know?...
