"what everyone needs to realize if that everyone&#039;s body is different n reacts different. you have to see what&#039;s best for you!!! you may react differently than the next person. i was on the shot for 8 months n gained 20 pounds and fell into a terrible depression. i&#039;ve switched and have been on the implant for 8 months now and have dropped 10 pounds! no depression! i&#039;m actual happy! no mood swings. i&#039;m very satisfied so far with the results. so my advice, find what fits you and your body. you may have to try a couple till you find a fit. but don&#039;t off of how other people&#039;s bodies reacted."
