I'm sure you can take psyllium alone if its for laxative purposes. I don't know how well it will work. Can you get the laxative tea? It is definitely worth it. I felt so much better after the last one, but I went back to my old lousy habits and felt terrible all over again. This is my second cleanse and I am on day 8 now, this time I am going to keep up the healthy eating habits when I am done. I believe that is key. Keep it up, don't give up!
