Hi, I’m 2 weeks clear from mirtazapine but I’ve started to get extreme anxiety again (insomnia, diarrhoea, waves of nausea, can’t eat, dizzy). I’ve had to call in sick to work today. Can I ask anyone who has gone through this a) is this typical of mirtazapine withdrawal, b) if it is, how long should I expect this to last? Just thinking that maybe this Is how I am off the drug? Just not sure whether to go back on them as this feeling is horrendous. Grateful for your thoughts.
