birth control
"I got the implant 2.5 years ago. In the first 3 months, I had crazy emotions. I was violent and depressed. I gained 20lbs but I don't think it's the birth control fault. I drink a lot more soda then I use to. I do not get a period at all but do agree with needing lube for assistance! Now that I'm in my last 5 months of it, I've been excperiencing the same mood swings from the beginning. Its  uncontrollable and scary. That's the only downside I have."
