I took Bentyl years ago and didn't care for it but can't remember exactly why. I've tried Bentyl and Donnatal but years ago when I tried them I took them on a daily basis and just felt drowsy and depressed. My question is can bentyl be taken just when needed rather than every day. I have become C again whereas I previously was D and years before that was C I don't want to take any antispasmodics on a daily basis. The pain is what gets me the most down.
