"i had the implanon for three years. never really noticed anything crazy except for the first and final month of having it. i had the usual nausea and dizziness. exactly what the doctor told me to expect.any medicine you take will have side effects &amp; sometimes you have to pick and choose your battles. i got a new one put it that same day i got the old one removed .i am now approaching year 2 of this one &amp; i am having it removed tomorrow morning. for the last year i have had on &amp; off nausea, headaches, moody, anxious. i am praying that once this things gets taken out i will be me again. my demeanor has been crappy the last year. headaches &amp; nausea prevent you from living your life to the fullest. absolutely do not recommend nexplanon."
