That's very strange that your doctor started with those laxatives first. I would recommend you try miralax or milk of magnesia which are both over the counter. How much water do you drink?
They had me on Amitiza 24 MCG capsules and polyethelene gylcol powder. I took the pills and the powder twice a day. I also ate fiber one cereals and bars. I have always ate alot of fruits and vegetables.
Welcome to the gastroenterology community! What laxatives did your doctor put you on? Did you try a high fiber, lots of water, lots of fruits and vegetables diet first?
