constipation, drug induced
"Awful stomach pain that lasted hours. Very small amount of diarrhea. Not worth the pain. I threw the medication away it was that bad. I didn't want to be tempted to take it again.Its really that bad. I wouldn't even bother halving the 25mg tablet. Also the fact that it seems to suck the options out of your body I'm in more pain that before  unfortunately I had taken my morphine before this drug. Stay away from it terrible medication."
