I have been on Phentermine since 4/10/2015. (today is 5/26/2015) My agression and anger has skyrocketed to unbearable. I am quick to scream and yell. I have also never been a violent person but have recently started a desire to punch or throw stuff when I am angered. I have also just as quickly gotten depressed and want to curl into a ball and cry. I got angry at a tree last weekend for no reason. I don't know what is wrong. The drug is working on the weight loss great but the mood swings are diabolical. Please help me. What are my options?
