Ten years ago I had severe anxiety and IBS-D. I had been prescribed LUVOX (fluvoxamine) and after about a month of taking it (25mg per day, a VERY low dose) both my anxiety and IBS had disappeared. My IBS is directly related to stress and so is my anxiety so maybe that is why it helped me so much. I have been off of LUVOX for a little over 7 yrs now, and just recently both my anxiety and IBS has returned.....now I have noticed by applying dietary changes, even without meds my anxiety and IBS is diminishing.
