I've been on 30mg Mirtrazapine 6 months for depression, never felt it did much except weight gain. After discussion with GP am trying to change to Sertraline. Was told just to swap one for another but having read posts decided to halve initially to 15mg.
The first night of going to 15mg had raging insomnia which persisted for 5 days. During the 5 days my anxiety increased massively to way beyond pre-drugs state. Ended up crying all night almost hysterically. Went back to 30mg for 3 days, was immediately calmer but really felt how sedative it is, but my mood hit rock bottom yesterday and I have felt desperate to end it all, along with feeling dizzy and faint.
I am about to start a new job in a week that I feel ill equipped for and have to take because of money problems - and after bad anxiety last week would have just stayed at 30mg and tried to come off it at a later date but going back onto the 30mg has made me feel so badly low and depressed again that I don't know what to do. Have GP appointment later this week but since they were the ones who told me to just swap over and not feeling confident of their advice now.
