"i&#039;m very frustrated.  i gained so much weight on seroquel, but felt great.  but, i continued to gain weight so switched to latuda.  i&#039;m miserable.  i cannot sleep, which of course makes everything worse. i&#039;ve tried it for a week and am having to switch back now. i hope i can find something eventually that helps me sleep and feel stable, but i don&#039;t gain weight."
