Nortriptyline
"I developed chronic diarrhoea in 2014 that started suddenly and never went away. After extensive tests I was given the diagnosis of IBS. The stomach upsets were so frequent sometimes up to 6 times a day that it was affecting the quality of my life. I could barely make it to the toilet on bad days. I have been taking Allegron/nortriptyline 20mg for 4 nights now and for the first time in years symptom free! It can make me drowsy in evening and morning but I am willing to put up with side effects as feel so much better. Pain free. I have also started a FODMAP diet and in conjunction with the medication and have had quick results."
