hi lynne888,reading your post ,I hope you don't mind me stepping in ,taking amitriptyline,does help in these sort of circumstances,iv been on it for over 4 years now for anxiety ,once I go to bed I do not get up to go to the toilet,i read that they can give it children to prevent bed wetting, in severe cases its taken for different things,in different doses,just wondering if it could help you in any way,could be worth asking your doctor,if you google it will tell you what exactly it does,x daisie
