Weight Control

Hey everyone, looking for some advice/experiences.

I started Mirtazipine 7.5mg about 3 months ago.

I have always been someone who watches what I eat and exercises regularly (7 days a week), naturally I have a slow metabolism but have been able to stay in good shape though healthy eating.

Is the side effect of weight gain mostly due to increased appetite? Hoping that is the case rather than a change to metabolism.

Hoping to lose a few kg whilst still using so going to track my food thoroughly.
