In A Recent First Time Use Of Donepezil I Had

In a recent first time use of donepezil I had an incredible experience that included seven hours in the emergency room. I had horrible diarrhea all over our home, I couldn't stand up, I had no clue as to what was happening, nothing seemed real, and on and on it went for around the six hours. The doctor said it was probable due to me taking two pills instead of one. Since I have some forgetfulness, I don't recall taking two pills. Help.
