I have been on NR for 15months. I liked it for a few months, but then it hit the fan. My face broke out with huge painful cysts and welts, the scars will always be there. I started to gradually gain weight (135lbs to 210lbs). My Dr told me that it was not NR over and over again. I trusted her (she was wrong). My sex life ENDED! I started to have Phsyco PMS Symptoms. Also my sleep was messed up. A mild head ache for months at a time. eventually my cysts started to spread. I stopped it even tho she told me not to. and since i have lost a lot of weight. Im down to 180lbs and i have not changed my diet at all. that was a month and a half ago. If you are having these problems STOP TAKING IT! its a new med and the doctors don't know all the side effects yet. Stop Before you end up like a 22yo with terrible stretch marks and scars all over for the rest of my life. Yazz is Wonderful. I might add.
