Girls, I have a question. Since week 4, I've been taking Dufaston. Three tablets per day. At week 16, the doctor reduced it to two tablets. Now, at the end of week 2, she said to finish the last two days with one tablet each. Today, I feel my stomach is calming down, and my back sometimes feels sore. Is this possible because I stopped taking it? Why is this pill so psychologically ingrained if I was not afraid to miss it by time, setting a reminder for Dufaston?
