Ethinyl estradiol / levonorgestrel
"I started Chateal four months ago. Bad  idea, I've gained 20 pounds, something extremely unusual for me cause I had the same weight since I was 15 and I've been having acne episodes which is even more rare cause I never had it before either. No severe mood changes but I've been very tired and sleepy too. 
Conclusion: This pill sucks I can't wait to change it."
