Started 15mg mirtazapine 5 days ago and within that time I have gained 5lbs. Not eating any differently so in my opinion it's the actual tablet that makes you gain weight. I have been regularly following an intermittent fasting protocol since march last year and within that time frame I have lost 33lbs. I know it's not what I am eating that is making me gain weight. Feeling very despondent, not willing to put my physical health at risk by carting around extra lbs. Anyone else experience this? Thanks
