Cilostazol Drug
Marty, hate that this is 100 years after your question, but my doc just gave me this for my cramping, i'm in the first 7 days of it where I only take one per day, after that it goes to two per day. It's really too early to tell definately but I do believe my cramping has slowwed down a bit.
(My legs, feet and toes start to cramp probably within 15 -20 minutes of laying in my bed - goes on intermittently most of the night)
the does for me @ 200 pounder

is 50mg tablet at night - then 1 tab twice per day.
