I just started the patch. I'm on my third patch of my first month. I have already experienced some huge side effects though. I started gaining weight (for me this is a good thing) just before I started the patch but since i've been on it, my little boobs have become quite heavy and full.. Not complaining, they're much more tender than they ever have been before though. I've had mild headaches, extreme mood swings including short periods of severe depression and other days where i'm so happy I wanna cart wheel. Hopefully i'll adjust better emotionally after a few more months.
