INVEGA, Thanks! :(

My psychiatrist tricked me. I was used as a test dummy. Was on Invega for around 2 years...FOR FREE!!!! Given samples, I directly asked would it cause weight gain and was really worried about the weight gain I gained approx. 35 on the invega. Over 100 lbs total since 2003!!! And get this, the very same Dr. gave me Zyprexa and Clonazepam. Poor choice for a Doctor huh, just go ahead and make me worst! End result I'm on A LOT of MEDS and the Doctors and drug companies are really making money off me now, that "Free" Invega has now nearly cost me my life. I am morbidly obese and have many issues. Thanks Doc!:mad:
