These are me new best friends.  I learned in my birthing class that if you are not sleeping or relaxing well then you are lacking Calcium and Magnesium.  Actually most people are.  These supplements were recommended because they are easily absorbed.  I went from waking up every hour to sleeping for 7 hours straight in about 3 days after starting these drinks twice a day.  That is good sleep for a 8 month prego lady.  I do remember vaguely trying to roll over a couple of times but not really waking up.  I also have been giving Izzy a half dose every night before bed because she is 6 and still was waking up at least once every night and after 2 nights she has not been waking up anymore.
