I have been taking dosulepin for over 20 years now, and now have citalopram added in too, and i expect if this continues to work for me this will be the same. I dont know many people who have been on meds for such a long time, but they are out there, and i suppose if it helps you, dont worry about the length of time, take diabetics who taken insulin everyday, or people who take blood pressure medication, i suppose they would all rather not, but you gotta do what you gotta do...
