Take ZMA before bed to keep muscles from tightening up, as well as aiding in recovery, take a 3min hot and 1 min cold series in the shower, pulse the leg muscles before bed with easy EMS, take arginine and/or niacin (easy on the dose!), self massage.
Scarface - I started a calf tightening thread a few months back and there was some very good input from the forum if you run a quick search - Charlie covered it all though.
My issues were probably very different from yours - but I found EMS particluarly helpful in my case.
Hope it helps.
