Hi Chewy, I had the same prob w/ gallbladder surgery. I had diarrhea for a yr, the surgeon didn't think D had any connection to my loss of GB. I went to gastro who put me on Questran, reg and generic later. Wow! I got my life back. I took it for 10 yrs. and never had a prob w/ it. I have been off it for a few yrs. and I think I need to go back on it. I have suffered w/ nausea for awhile I have been given Promethazine, also. Originally, I was given 10 mg., I had to move up to 25mg. It does make me tired, so I don't drive w/ it. My DM had her GB out 6 months after me, had same prob. w/ D, they gave Questran, and it didn't help. She didn't stay on it long. She has gone back & forth with D and C. She has been dx w/ Gastroparesis, so it is one heck of a ride.
See if the new meds work for you, sometimes it takes awhile for meds to settle in your system. I wish you good luck. God bless. Alice.
