Atropine / diphenoxylate
"I'm a 32 y/o female who has suffered from chronic diarrhea related to anxiety for about 5 years. I have anywhere from 2 to 10 bouts of diarrhea a day. I was very excited to try Lomotil after reading so many positive reviews.

I have been taking 2 pills 4 times a days, as prescribed. This medicine did not work for me, and the side effects are awful. I am still having urgent bouts of diarrhea. Also, this medicine makes me feel so sleepy that I can barely hold my eyes open. I took my last dose about 18 hours ago, and still feel very groggy. The dry mouth is so bad that it wakes me up, even though I have been staying hydrated.

I am discontinuing this!"
