high blood pressure
"I am a 48 yr male and have been taking as directed 50mg day for 6 months, blood pressure now 125/80 and stable. I drink approximately 1 liter of whiskey every two days and notice no other side effects other than I cannot maintain an erection for as long as before taking this. I should mention that I've been drinking this amount of rye since I was 20yrs old and that this is the only medicine I take. "
