"live in the uk. got this because naturally my mood swings were crazy (very extreme &amp; hormonally-driven) &amp; i wanted to stabilise them a bit. i didn&#039;t take it for birth-control, happy with condoms. took the same drug in pill form for 3 months to see what it would do to my moods. naturally, i suffer from my hormones: grumpiness, sex drive and appetite are erratic, hated it. the pill did seem to stabilise my moods, so i had the implant put in. it has been 3 years, only side affect may be weight gain, unable to say if that&#039;s just me getting older (30 now). if you&#039;re not sure if you&#039;ll like it, why not try the pill version first before you get the implant?"
