"worst thing i ever did! i have had the implant in my arm for around 2 &amp; a half years, i didn&#039;t want to wait till the 3 year mark to get it removed so i had it taken out today. i gained 28lb from having it put in my arm with no lifestyle or diet changes. it made me angry and always sad/depressed. i used to be so happy &amp; calm and never got mad easily, but with the implant in i snapped at everything &amp; had terrible mood swings. it effected me mentally. my periods were v irregular, i could be on for 1 full month &amp; then off for 2 months then come on for a week &amp; so on. such a horrible life changing drug. the worst thing about it for me was the weight gain, i used to be slim and fit and now i&#039;m fat, gone up 3 dress sizes! :( not good!"
