I have been on zyprexa three weeks now, have swelling of the ankles and legs, dry mouth at night, have to sip on water a few times. Tongue sticks to roof of mouth, mouth so dry. I also experience blurred vision have to keep blinking my eyes. I am on 5mg in mornings and 5mg at night.... voice seems to get hoarse if I speak for a length of time... Also can't seem to concentrate on reading anything for too long... Don't know how long I will be on this pill, can't afford weight gain, have 70 to lose as is.... sincerely Judy
