I am so relieved to come across this forum. I have been on Yasmin for about 3 years. After reading several postings here to my husband, we were both horrified to hear that I wasn't the only one having strange issues without a clear cause. I too have had heart palpitations, anxiety attacks, uncontrollable mood swings, inability to concentrate at work or deal with normal work stress, back pain, trouble falling asleep, low sex drive, and most recently, horrible depression. I have been to psychiatrists, allergists, chiropractors and physical therapy - all to try to find the cause. I have just gone off the pill, and have noticed improvement so far, and am very excited to see it hopefully improve. Hopefully I will be able to find a hormone-free birth control, instead of dealing with this. I can't believe doctors do not discuss these possible symptoms with their patients. I never would have thought bc pills would cause anxiety, depression, etc. A huge thanks to all of you for your candid comments... and helping me find an answer to my life-altering side affects!!!
