Mamacaz it sounds like you've been nutritionally deficient for a really long time. It may take a long time to build your bones and muscles back up. You probably get enough exercise chasing after your kids, so I wouldn't worry too much about it until you find yourself wanting more exercise. Keep your protein up and let the nutrients work on you for a while. A month isn't very much time. I didn't see any change for a month and was pretty bitter and disappointed and certain I must have hormonal problems. I think now that I'm perfectly healthy and just impatient.
