Nifedipine
"Been taking for several month and swelling in my ankles and calves are a minor issue.  First thing I do when I come home from work is put my feet up for about 30 minutes and that helps. Within about an 1 1/2 hours after going to bed I have to get up to pee, I think this is caused by the fluid build up.  Blood pressure has been very good on this, about 126/85.  I do feel tired and do not seem to have much energy most of the time."
