My experience with Yasmin was horrible. I originally was on it when I was 18, and it was great. No side effects whatsoever. I'm 23 now. I stopped taking it approximately 3 years ago. When my doctor recently prescribed it to me, I was excited because of the positive experience I had once had. WOW! I only took it for a week before I stopped completely. Everyday I woke up not only with a headache...I woke up with a severe migraine. I was nauseous constantly, eventually leading to either diarrhea or vomiting. I was completely lethargic. The worst side effect of them all had to have been my complete and total mood change. I was barking at my friends, co-workers, and boyfriend. They ALL noticed a change in my demeanor from Day 1. I'm not on any other type of medication, so there was no reaction to any other chemical in my body. I felt so sick, I even missed work for 3 out of those 7 days. Once I stopped taking it, my original symptoms have gone away completely. I am experiencing a little breakthough bleeding, but my headaches have stopped, no more nausea, and I'm back to my old self. I just wanted to share this with you so that I may help some other woman feel a little less crazy, as the other testimonials have done for me. Thanks!
