I started taking Femcon FE about 4 months ago. I haven't had a good nights sleep since. Other side effects I have suffered from are nausea (after taking the pill no matter what time of day/night), headaches/migraines, VERY low sex drive!!, insomnia, increased appetite!! especially for sweets, extreme fatigue and severe mood swings. I have however, experienced no break through bleeding and have had a very regular period, 28 days to be exact. I love that about the pill but the side effects for me are enough for me to stop taking this pill. My husband mentioned that maybe this pill was causing my insomnia and after doing some research and reading other comments here I feel that it is this pill. So....thanks to all who post here. You have helped me greatly! Now maybe I can get some much needed sleep.....zzzzzzzz....zzzzzzzzz AND SEX!!!! :)
