I've had one in since May 2010. I definitely love the fact that I don't have to remember to do anything, because while I was good about remembering to take the pill every day, I sucked at taking it at the same time.
I was told that 1/3 of women have their regular periods, 1/3 of women have worse/more frequent periods, and 1/3 of women have fewer/no periods.
I was really hoping for the no periods
, but I seem to still be in that 1/3. I bleed about every 6-8 weeks, about the same level of cramping as on the pill (less than w/o BC at all).
Not sure about acne issues as my face has never been clear
, so either my body doesn't like the hormones at all or it just refuses to stop spotting. Still, it's no worse than it was on the pill, either.
No depression, no nausea.
My only complaint is that it hurt like crap for the first couple of weeks - anything brushing it (sleeves, brushing my arm against something) - would really hurt. After scar tissue built up, or my body got used to having it in, or whatever, it's fine. I can feel it in my arm, but it doesn't hurt unless I'm giving blood and they stick a tourniquet right around it.
Hope that helps.
I do like the implant, though I'm considering getting an IUD when this runs out, since it lasts longer and has the hormone-free option.
