Psyllium makes me bloat up like a ballon. Learned that pysllium is highly fermentable. Intestinew did not do much for my bowels. One tea bag of senna mixed with a little vitamin C is much more effective. Dont recommend it all the time..can cause some cramping.
Try eating a large handful of pumpkin seeds for constipation. They work every time for me and dont cause cramping.
Dews Bile salts get the bowels moving ,along with doing enemas.
