I did not have this experience myself but I know a lot of the other women had something similiar. However with all weight gain I think the most important factor is to increase your activity during the day. Walking works best for me (and it does not cost anything) I am not sure dieting works for anyone, its very important to keep up your nutrition and ensure you are getting enough protein and vitamins otherwise your health will suffer.
On the plus side a few extra pounds can be very flattering to the face, the worst look I always think is someone who is too thin when they get over 40 as it really shows in the face.
