I had terrible fatigue and mood swings, I could feel it but not control it. I tried through diet with no avail. Within the first cycle of the progesterone, my mood swings we DRAMATICALLY improved. My relationship with my husband is more loving and my teenage son with truly talk with me again since I can be rational and not emotional. I was unable to lose weight until I started the NP Thyroid, which my Dr. is so excited I'm down 48lb! These two are vital to my health and my mental well-being. My family is so grateful!
