I've been on Mirtazapine for a while now and used to take them at night. I decided to change to Sertraline 50mg which I take in the mornings, but I've been feeling pretty awful since taking them - only getting a few hours sleep at night, sweating episodes, etc. I've been on them for two and a half weeks. I don't want to keep taking them and prefer to go back to Mirtazapine because they helped more with sleep. I've also had a big reduction in apetite. Has anyone else had these symptoms with Sertraline?
