I am having trouble doing #2 daily. It usually takes me 4 or 5 days and then, its usually a small amount . OI do drink a large cup of water each time I take (twice daily ) two 25 mg pills along with 3 50 mg primidone pills. I am also a diabetic who takes insulin. Is there anything you sense. I use to drink 3 or 4 cups of coffee daily and had a reguular bowel movements.
