All of the posts above are great answers, psyllium, with a bit of senne at first otherwise it will clogg, plenty of water, with a dash of cayenne and lemon juice. Enemas (colemas and colonics if you can afford them)... but one should not forget, we get magnesium deficient with candida and it is utterly important to supplement for candida depletes magnesium, insufficient mag. will cause constipation and long term it will get to your muscle, you will loose muscular mass and you will get muscle twitch, simply because your metabolism goest into your muscle to get the mag. it badly needs.
