Plavix and slew

my 85 yr old father had a slight heart attack recently. they put in a stent and a pace maker and sent him home with a slew of prescriptions- lipitor, plavix for 4 weeks, 2 BP meds, nexium for his daily baby aspirin.
he decided to only take the baby aspirin and a licorice supplement i gave him to protect his stomach instead of the nexium.
his doctor talked him into taking plavix for 14 days but he gave up on lipitor. he knew dad would never take it.

anyway, i talked to dad tonight and he stopped taking plavix after just 9 days. he didn't like the way it made him feel. he said it made him tired. he felt great before he started taking it and he's feeling better now that he's stopped
