Yasmin nearly drove me crazy!!!! I have been on yasmin since it came out 4 years ago. It worked great at first. Started taking it for my skin which dramatically improved within 2 months of starting yasmin. But then i started to develop extreme anxiety. Irrational thoughts and fears were part of my day, every day. Then i was diagnosed with B12 deficiency. Next came the weight gain and headaches. I still had not linked all of this to the yasmin. I then developed a very painful cyst in my breast which went away during my pill free week. My eyesight got very bad which was alarming as i have always had perfect eyesight. My anxiety was so bad i was prescribed xanax. Then my skin started to get bad again. I stopped the yasmin to see if this was the cause of my problems and slowly my problems began to subside. Except for the anxiety. Within 2 months of stopping yasmin i have lost the weight i put on. All of the weight was around my waist and hips. The cyst in my breast has gone. I am now been treated with low dose naltrexone for a damaged immune system which i feel was cused by yasmin and feel like i have been given a new life. Anxiety gone, skin great, eyesight improved. I know that the yasmin caused my problems. It was great at first but the long term effects are horrendous. I feel strongly that much more research needs to be done on the long term effects of this bcp. If anybody else has had the same experience please comment here as it would be interesting to find out if my feelings about yasmin are true. To anybody considering yasmin i say BEWARE!!!!!!
