I feel like I may get addicted to Percocet because I'm bipolar...?

I was recently diagnosed with bipolar disorder and my psychiatrist prescribed me Zyprexa(2.5mg) and I can't stand it! It mellows me out and makes me a zombie. Well anyway, I got hooked up with some percs the past couple of days and I love them so much because they make me cycle to mania whenever I take them.. and I love it when I go into mania. Thats the only time I'm energetic and actually happy... so if percs make me this happy, I'll definitely get addicted.. help?
