Welcome back Dody!! Glad to hear you are getting all settled into your new home. I just got off my treadmill and was feeling good about 1 1/2 miles. Good for you doing 4 1/2. Makes me miss my Texas winters where I had a walking buddy and we would do 3-5 miles a few times a week.
Crystal light has aspartame; same as most diet sodas. It doesn't have the carbonation so at least it shouldn't affect your bone health.
Time for a grapefruit and yogurt for my breakfast.
