"i was on 20 mg latuda with 300 mg lithium. it was the most normal i have felt in a while. for me it has being weight neutral in comparison with zyprexa. zyprexa made me gain 5 pounds per day &amp; 80 pounds in a few days. latuda gave me more energy to work out. naturally, if i don&#039;t take meds i don&#039;t even have to work out &amp; have a fast metabolism &amp; loose weight easily. with meds i need to exercise. however, the main difference is that with zyprexa i would exercise 5 times per week, 2 hours per day, eat healthy &amp; still gain a ton of weight. latuda helps me maintain healthy weight. unfortunately, my doctor for some reason decided to increase my latuda doze to 40 mg. i am now having muscle spasm, around my eyes."
