I've had FMT and have suffered from constipation before, though nowhere near as bad as you by the sounds of it (i'd go every day or two but only produce small amounts of rabbit droppings) since FMT I have been pretty regular, producing a decent stool mist of the time - but I'm also eating loads more fiber. I'm generally on a really healthy diet but both diet and FMT haven't completely resolved bloating issues. But yes, the constipation is pretty much gone.
