Weight gain on mirtazapine and how to lose it?

I have put on stone since taking mirtazipine,any body have any good tips for losing the weight and keeping it off.dont want to stop meds want to give it a good try but need to lose weight

I put on weight when taking too as had a huge appetite and always felt like I could still eat, never full. Can you up your activity levels to burn more calories, I started doing a Zumba workout every day and also tried to keep busy so I distracted myself from snacking. I ended up stopping taking them because they did nothing for my depression and anxiety and the only benefit was a decent night’s sleep so I found other ways to wind down and relax to help me sleep.
