"several of my friends have had positive experiences with no side effects but unfortunately i can not say the same about myself. i have had nexplanon for 10 months and i am going to try to get it out soon. i have never before been dizzy and now i have vertigo all the time (lately every day) which makes even walking hard sometimes. i&#039;ve gained 30 pounds, have insomnia, and am moody and depressed."
