Hi Nicole-hope this helps:Bentyl is like a muscle relaxer for your insides. I get a pain in my right side when things slow down or don't happen. this med has helped me sooo much.The reglan is used to treat adic reflux b/c it gets food through the system at a faster pace- my problem is very slow motility so this helps me tons. I can go after meals b/c I take time & drink hot tea or coffee. I used to take propulsid but they pulled it off the market due to some folks had heart failure from it.
