Mirena

Hey ladies! You were so helpful with my last question that I thought I'd ask you guys for your opinions! I was just at my doctors office, and I asked her about more reliable methods of birth control than the pill( I take mine like I'm supposed to, but she warned me that if you throw up/ have diarrhea then tit won't work.) so I wanted to try something that I wouldn't have to worry about. She recommended the Mirena, what do you guys think? Have you tried the Mirena, or have insertion tips or anything?
