I was on it for a couple of years. What good is not having a period if you have no real sex drive? Also, I felt that my personality was very suppressed and dull. I am usually an upbeat and outgoing person--it was like I had blinders over my eyes constantly. When I got off of it, I instantly felt better and more alive! I switched to Loestrin24 Fe--then came the side effects!!! (See Loestrin Side Effects) It was as if switching from Seasonale to Loestrin put me in peri-menopause--I'm 37. I had 6 of the 8 symptoms for two months. now, it has been 4 months and still no period. Apparently missing your period after going off of the Seasonale is quite normal. My Dr.'s office was not worried for the first couple of months. I now have an appointment on Monday.
