I have been taking Zyprexa (and Zoloft) for 2 years. I have gained 70 lbs. I have no energy. I do not have a full range of emotions. I am now very agreeable. I don't have reasonable reponses to things/situations. I sleep a lot, I no longer exercise at all. My weight gain is a real issue to me. I recently learned that Zyprexa has been linked to diabetes, which my dad died of two years ago. I STOPPED taking it 4 days ago, and have gone thru really bad withdrawals: itching, acheing joints, tremors, severe anxiety, not sleeping, sweating, then freezing, not able to relax, can't get comfortable...I'll let ya know how it goes...
