Constipation. What should i do?

Hello Sir, I have been suffering from fissure. Consulted a Gestrontologist. He prescribed, Confinex 2 mg 1 tablet after food, Muvmend 15 ml after dinner, Sompraz L 1 tablet empty stomach. I started taking these. But on the very first day itself, I had motion 3 times. First two times stool was deep green. Third time was only water. Day 2 and Day 3 I had motion twice. Second times are normally liquid. Day 4 I stopped Sompraz L and didn't go to 🚽 second time. It created heavy gastric and I had heart ache the following night. Next day I consulted the doctor once again, He prescribed Normaxin 1 tablet after dinner. This tablet relaxed my heartache and all. But the very next day my stool become harder. Still, I continued taking the medicine. Today morning the stool was even harder. I don't understand, what should I do? When I don't take Normaxin, Because of severe gastric it makes me restless. If I take Normaxin, It's making my stool hard.
