Curious who lost weight after removal with no change in lifestyle.. and how long it took?

I just got mine removed today, I gained a ton of weight in my face, neck, arms, and stomach, like all of my upper body gained weight, even my HANDS. I feel like it also made me have insane mood swings, and completely took away my sex drive. I really don't care about the latter as I am celibate and have been for a year and a half now (focusing on career & school) but I really want to lose the water weight and to stop being so damn tired. I do plan on joining the Y next month and working out a few days a week because I was a total sugar addict couch potato with the nexplanon in, when before I was super active and full of energy.
