Sensativity symptoms and conditions

I went on the ring about a year ago and I have loved it. I have been having a problem when I drink too much alcohol though and I am not sure if it has to do with the ring. Whenever I drink to the point where I don't feel good and I have a headache, I get really suicidal and freak out. My boyfriend noticed a few days ago that these episodes started around the same time I got the ring, but we aren't quite sure. Has anyone else ever had any experiences like these? I would like to know as soon as possible so I can take it out. Also, I would like to know if there are any other birth controls that people would recommend besides the pill. I don't like having to remember to take them every day.
