I have been on this since December 2008. It was prescribed for me because I had D since 1993 when I had my gallbladder removed. It originally took 4g twice a day, mixed with water but have since reduced it to 4g once daily. I originally used the orange flavored one but switched to the sugar free lemon-lime flavor. It works like a HOT darn! I love it because now, other than when I am flaring, I RARELY ever have D. Thoughts of "where is a bathroom" no longer rule my day. I am no longer scared to go on road trips, snowmobiling, boating, etc.
I don't find the taste bad at all, but the texture is a bit gritty. If I let is sit for a few minutes before mixing it, it lessens the grittiness. Make sure you don't take it within a few hours of other meds in case it binds with them. The only problem I have with it, is that it gives me heartburn occasionally so I usually take a Zantac (150mg) about an hour before I drink it.
