Please help with medication

My doctor prescribed me mirtazapine 30mg (evening), pregabaline 50mg (3 times a day) and quetiapin 25mg (for sleep) almost 3 weeks ago. I‘m diagnosed with severe depression, anxiety and panic disorder.

Since taking this medication my NES (night eating syndrome) is just BRUTAL and out of control

I‘m talking about waking up every hour and eating HUGE amounts of food like a whole pizza, 6 snickers, half a jar of nutella, a burger…

So of course I wake up feeling nauseous and start vomiting to relief myself from the pain Also, my morning anxiety is killing me before taking any pregabaline, is this normal?

Any kind of advice is appreciated, thanks
