"i&#039;ve taken zyprexa as an adjunct to lithium for bipolar i. my thoughts are slower and it has gotten rid of any anxiety (this i think is the best side effect). i have not had issues with weight gain. i change between 5 and 10 mg per day and how i feel. sometimes it can cause me to sleep late and need to take it earlier in the evening to avoid that.  great medicine to keep me stable and stop intrusive thinking."
