Walking but it isn't enough. We don't have anywhere like a Y to swim here but I think the state park a few miles away will let you swim for a fee. Once I'm out of credit card debt soon I'm going to try swimming 3x/week to see if that helps. It's only a little more expensive than Curves and the driving distance helps level that out (unless they've increased their swimming fee).

Do you feel you know your body well in terms of how it reacts to meds?
