I went to Long Beach today to pick up my Zelnorm and took my first pills tonight,while I was there I asked my Doc if the zelnorm study was closed. He said defintly not, they are still enrolling. The study protocol number is CHTF919D2201. The study is for functional dyspepsia, my doctor believes 9 out of 10 IBS-C suffers have dyspepsia. If you would like to know where the study groups are and if they are in your area, I could see if I can find out. Just let me know where you are from. Marvin
