Need HELP!!

Is anyone on Metformin? I have been on it for a few months now and just had my first ovulation after my first period in years. I know it's helping my body get back to normal. But, my hormones have not been balanced for so long and the Metformin is suppose to help with this. Has anyone dealt with random anger, short temper, or just freak outs in a rage style? I really hope this isn't just me. Because then it means I'm just crazy.
