I thought I was going crazy until I found everyone's comments. I started Zoloft 3 months ago and I'm having vivid dreams. So much that when I wake up, I have to think if a conversation or outting really took place or if it was a dream. I haven't had any nightmares, my sex drive is also down. I have no interest in sex, and I seem to be able to sleep for hours on end if given a the opportunity, such as the weekends, I seem to sleep for 12 hours straight.
